I had to change the neon sign outside my house from “I’ve always had mitochondria” to “I’ve never had mitochondria” and then I had to throw that sign away because it was inaccurate. I *had* had mitochondria in the past, I just didn’t have any in the *moment*.

I've been listening to Hank Greene say "The powerhouse of the cell!!" since I was in high school.....I'm almost 30. 😁 Keep it up Hank!

Saw a video about a man on a hike, boulder rolling down hill towards him, he lifts it off and up and over. Deflecting it. Hulk style. It's thought almost all his ATP was burnt at once. Unknown trigger mechanism. He spent a year in a hospital, weak and helpless, before he slowly recovered.

It would be great to make a series on the most commons micro-organisms founds in our gardens. For those growing organically, the plants are growing thanks to the billions of micro-organisms at work into the soil, eating the organic matters on top and producing secondary products, available for plants as fertilizer. It would be extremely interesting to see those micro-organisms in action. I'm sure all gardeners would like it. I have not seen any video like that anywhere.

I keep getting what I think are random new channel recommends only to find out it’s just hank. Not complaining.

Hello, I'm a huge fan of your work and I'm currently in the process of writing a book on eukaryogenesis and the origins of metabolism. With that said, I was wondering if you guys at journey to the microcosmos would ever consider doing an episode (or perhaps a couple) on the discovery of Asgard archaea, the E3-model, and the energetic bottleneck as described by Nick Lane and his colleagues. While giving a more nuanced take on primary endosymbiosis is a daunting task, you've all shown how science communication doesn't always need to come at the expense of providing detailed descriptions of evolution and cellular processes. Who knows, it might be a fun challenge ;)

I don't know anything about micro-biology but it's utterly amazing to think there is another world that exists within our own, and just watching these organisms (if I can call them that) go about their business makes me wonder 'what drives their behaviour? I want to thank you for sharing this amazing footage it just shows there is so much we have yet to understand.

I love that there are always exceptions in nature. Goes to show that everything isn't black and white like humans tend to paint.

In graduate school I researched lipid biogenesis in mitochondria, and that phrase is in my nightmares.

I don't know if you have done so, but looking at fungi under the microscope should be fun/informative

What a convoluted path!

I've seen scores of your videos and I feel this is your best production in this style.

"Pissabed" is another name for dandelions, if anyone's wondering.

What a beautiful way to summarize such a complex topic. Thank you.

One has to be careful when trying to guess the evolution of parasites. This clip should have mentioned henneguya salminicola, even if the channel is dedicated to microorganisms, since it matches closely the subject matter. And the animal is quite small.

Another AWESOME and fascinating video!! In addition to the sources cited above, the book, "The Vital Question: Energy, Evolution, and the Origins of Complex Life", by Dr. Nick Lane, reads like a suspense thriller novel, as he discusses the research and evolution about mitochondria. (Seriously, this is a SCIENCE book that you won't be able to put down!) Even another viewer, Kyle Rosenberg, recommends his work! Thank you, Microcosmos!!

i never realized that meme was poking fun at "useless information in school" but i love watching this channel so i guess it makes sense thatd go over my head lmao

If there's one thing I'm taking away from this video, it's that mitochondria is the powerhouse of the cell.

Thanks for that beautiful journey!

Excellent visuals 🎉🎉🎉🎉 and narrstion ,helps to understand these somewhat complex organisms ,Thank You.

it still bothers that Hank pronounces the W as a V in van Leeuwenhoek it is a Woo sound in dutch not a Vee sound.

I would love to see Journey through the microcosmos at Nebula

this is a huge video! WOW thanks!

Fascinating, thank you so much

Great video, thanks.

I feel like this could provide a useful tool for the study of mitochondria, a transplanted mitochondria from similar relatives could provide a similar process to the first integration of mitochondria, easier said than done but life did it before. Maybe it'd work like the Pokemon daycare, drop off the two compatible parents and boom, an egg lol.

I was always wondering about this after studying Cancer and the importance of ATP and Mitochondria for its production and Apoptosis and a regulation of Calcium -Maturation of T cells

Absolutely fascinating

Without mitochondria you could never carry oats. You could never even harvest oat, or sew them, or even make a farm to get them.

❤ thank you Hank!

mitochondria is the powercell of the house

the most amazing thing about the mitochondria is that it's actually a cell living inside another cell...

great video!! it would be great if there is more video about evolutionary concepts !!

No one still uses the term "Archezoa" anymore because it is not a monoplyletic group. Mitochondria have been lost in various lineages including ciliates, euglenozoa, and even fungi. Oh, and yes, Diplomonads too.

Just wondering if James is going to publish another book. I would love to see him publish one on the collection, care and feeding of microbes.

Were... were we looking at poop this whole time??? I'm sorry, but when he told the story about van Leeuwenhoek, I couldn't get it out of my head. Every time there were diplomonads on screen, I kept thinking, "Is that poop? Am I looking at poop?" And the large brown indistinguishable bits weren't helping. 🤣🤣 Awesome vid as always!

I feel like Hank’s voice was recorded while dreaming, that’s the only explanation for his calm and collected demeanor when talking about science

amazing, I remembered the PS1 game parasite evil 1🤣🤣🤣

The Powerhouse of the Cell? Ayyo, let’s go

You should see history or Economics or philosophy in public schools

I love watching stentors eating. Thanks for the footage! Thanks for the video😀👍

I was pleasantly surprised when I realised it was Hank Green narrating!

Everyone better have clapped when he said the thing.

I miss the ultra calm Hank of yore.

lol a "Pissabed". Or potato bug! Or Wood louse.

I've been using the image generator, and I LOVE it! 100 searches didn't take long. I tried to sign up with a third e-mail, but they require a non-voip phone number for verification, and only allow 2 accounts per phone number. Did you run into this problem while testing it out?

My brain just locked onto a minor issue and wouldn't let go when it was stated that microganrisms were "our invisible friends." They aren't really invisible but instead they are smaller than our normal perception is able to see. Wouldn't a better work be subvisable? If we talk about sounds we don't say that elephants make some noises that are silent, but that they make some sounds that are subsonic, to describe how they are lower than our ears can perceive them. In turn sounds too high for us to perceive are supersonic. Why does it seem that only when we talk about small things we might say invisible, when in fact they are just smaller than our organs of vision are able to perceive? I think I prefer subvisable as a much more accurate and descriptive term.

The original Archaea was a goldfish. It had no real digestion, it just ate and processed what it could. Constantly eating. An alphaproteobacterium got eaten. That alphaproteobacterium basically was able to freely exist in the same environment as the goldfish food, but they were rarely (or never) digested. They attached to the inside like a remora. All the alphaproteobacterium ever did was produce as waste whatever the goldfish could most readily digest. The flagellum became vestigial once the pili are attached like velcro and directly integrate. Flagellum/pili becomes a docking station and the rest is history.

Noticed we need to breathe more when more energy is available heat electricity to light. Maybe ATP is to make energy usable catching it storing it and releasing it

7:30 Me parece que esos grupos de hierro se usan para estabilizar el ADP

Aí que ótimo. Consigo ouvir o vídeo em português agora.

I'm sure once in a while it's the cell's resident pretty-boy. I mean, there are so many pictures of it, right?

Videos like this makes me glad I was born a human.

Looking at designing wires molecules for storing and transferring energy . DNA 🧬 list exact structure

Mitochondria, it's the warp core of the cell

They have little arms that stretch out from both ends that seem to move the diplonomad cell around. Strange.

Always a pleasure to travel to the microcosm with Hank and friends!

I have a couple ideas. I heard dish soap stays on dishes in some cases and we eat the residue. Could you wash dishes in various ways and check for soap residue after they dry? Secondly, could you get two small things of milk. Both set to expire in 5+ days or so. One carton you open and pour out half the contents. The other you do not open. Keep both in the fridge until it's 24 hours past the expire date and check them both. Which would you rather drink?

0:16 PIA is actually good asf vpn. Idk about the price now but I pay 5$ I got subscription back in highschool and kept it ever since

Maybe those oxygen free eukaryotes might dominate Oxygen free planets

2:12 Soy de México y aqui siguen con sus leyes de mendel, nisiquiera hablan de Margulis y la teoría endosimbiotica

Grammar nitpick: Title should be either "Are the Mitochondria Always..." or "Is the Mitochondrion Always..."

I just realized today after all these years... That I recognize that voice!!

How can these organisms make ATP in the cytosol if ATP production otherwise seems to require a membrane?

Yess

Do the microorganisms have microorganisms of their own? Like smaller ones we can't even see?

Does anyone know any good microscopes under around £90 ($110) that can go to around 1000x - 2000x?

Liquid rock is called "magma"

Interesting.

I also never figured out how the DNA of the Mitochondria DNA gets transported to the Nuculse of the cell

Somthing *exists* Scientists: but why are you like this

*rewrites the kym page to say "the mitochondrion is the powerhouse of the cells of aerobic eukaryotic organisms"*

THESE CLIPS ARE JUST TOO MESMERIZING TO WATCH

Cool.

“Is the mitochondria the power house of the cell?” Me with a condition that means my cells are constantly throwing away energy and causing chronic fatigue: Absolutely not, please roast those lazy buggers

Cool

I have a small suggestion for the editing team of Microcosmos team. Please show us the real time video first before showing the slowed down of sped up version of the slides.

I'm almost certain the mitochondria meme started with an episode of Sabrina the teenage witch. Sorry I'm thinking of mitosis

I just want you guys to know that this channel serves to re-enforce my awareness of the extremely horrifying nature of life, and humanities extremely violent journey to the top of it. Every time I watch it, I have an existential crisis. Questions like: - "Why are we made of cells working together" This show answers with: "Because the concept of hell that humanity has known for all existence is actually the ancestral memory of the micro cosmos coded into our DNA" - "Why do we fear death?" This show answers with: "Because technically we have never experienced death since the beginning of life, but it is everywhere and it looks awful" and my favorite - "What is pain? Or to be more specific, can pain in the world be reduced. Can it be measured." This show answers with: "All around you, at any point in time, is pain beyond measuring. Pain so horrendous, it is at its core, the existential dread of life of the organisms pattern itself screaming in protest over its own destruction. Since at no point in the existence of your cells, have any of them ever experienced death, the pain your experiencing is a multimillion year scream of horror. And its happening everywhere, all of the time. So no. Pain can not be measured, increased or reduced. Because every creatures death is technically an infinite pain. Just because you cant hear it screaming, doesnt mean it wouldnt if it could. Do not seek to reduce pain, but to make the pain have value." That last one I came up with when I saw that organism that punched a hole into the other and sucked out its insides. I do not begrudge the darker parts of our nature at all anymore, after seeing where we came from. It was necessary. I cant even watch the videos anymore, even though they are fascinating. The calm detached voice makes it worse somehow.

6:15 - introvert with their extrovert friend

Could Mitochondria exist in isolation, out of a cell?

Unmmm at 7:15…. In the right half of the screen… what are all those????

Hank is a Kraken fan?

isnt it more likely that archezoa are actually mitochondria and vice versa but develop accordingly depending on the environment?

Can someone summarize evolution of rotifers for me? Are they ancient, primitive animals? OR are they devolved/miniaturized more advanced animals?

El problema es creer que la mitocondria solo tiene como única función la energética.

Mr Green, why won't you tell me if you ever met Mr Evel Knievel?

The exception proves the rule

Wait is this hank green?

How can mitosomes persist across generations without DNA?

Slowed down 400%? If you slow something down by 50%, it is at half speed. If you slow it down 100%, it is at a stop. How do you slow something down 400%? If what is shown is at 1/4 speed... well, then it's been slowed down 75%.

Missletoe's lack of functioning mitochondria is weird.

Wouldn't a "don't know theory" be more productive in trying to understand cells, since we continually get it wrong trying to link it with the theory we have. ....from Ireland.

am i hearing hank green?

6:30

Is the use of "powerhouse" in the literal sense familiar to native English speaking kids nowadays? Does anyone actually still use that instead of "power plant/station" to refer to industrial facilities where electricity is generated? For the longest time, I only knew the metaphorical meaning (e.g. "China has become an economic powerhouse."), so the "powerhouse of the cell" sounded even less helpful... (In my school in Germany, we learned that ATP is the energy currency within the cell, so other, more unwieldy forms of energy like glucose have to be exchanged into it.)

So … what if you transplanted mitochondria into them?

well i mean the mitochondrion lies within the cytosol, so one could say its true for everything

who decided to name something pissabed
