Hey Guys! Two quick corrections. 1) Protein CAN be transformed into glucose through gluconeogenesis 2) As Amat said, "The orange box is supposed to say 'adenine' not adenosine. Adenosine is a nucleoside composed of adenine and a ribose sugar."

I use this video for my biology class every year. No one else explains it so well and concisely.

Thank goodness our bodies do all this by themselves. Imagine if we had to think about all this and understand it, and remember to turn on and off these generators!

Why does the music sound like this guy is going to change my life with a useless product following an uplifting story?

1 hours of class failed to explain this as well as you 9 minute video thank you :)

This seems like such a great explanation... yet I still don't understand a thing

I'm really happy I ran across this while studying for my test. Words by itself confuse me sometimes. It's nice to be able to see a visual perspective on anaerobic and aerobic. Thank you!

now imagine all the professors at college explaining this to us, yet failing miserably...........

me: clicks on clip scrolls to the comments for help.

This is the best breakdown of anerobic vs aerobic exercise that I've come across! Thank you for adding so much clarity!

As a runner I often see the terms aerobic and anaerobic training passing by. But now finally I understand how it actually works. Especially the anaerobic raised some questions for me. Well explained!

I'm training to be a PT and this concept always really confused me. Thank you for explaining it so clearly!

The absolute best explanation of multiple subjects I have ever seen. Excellent stuff! Keep up the great work Dorian.

Wow! In less than 9 minutes viewing your video and my mind is full! Thanks for packing all that info into an easy to mentally digest format. Much appreciated!

Very well explained. Thank you for taking the time to put together such an excellent video. Being a type 1 diabetic it gives me major insights to this topic and my HUGE takeaway from your video is this: any exercise can be made anaerobic or aerobic, so it’s not just the “exercise” you perform, it’s more about how you “perform” it. Thanks again!

“average bro who trains” lmao

Thank you so much sir, even a non medical guy would learn it easily, literally too much simplified and precisely explained thanks alot, lotsss of love and respect ♥️

Weeks of learning this in biology built me a foundation but you made it make more sense. Thank you!

This was Great video! Well thought out, explained and managed properly. Nice work man and thanks for taking the time to make this, I'm sure it will help a lot of people!

Now, can you please explain how Eliud Kipchoge can run 26 miles in 2 hours 1 minute and 38 seconds? I would not be able to keep up with his pace riding my bycicle!

Thank you so much for this! I’ve been trying to understand this for a long time and always get confusing answers. I just subscribed. Thank you again

I have Chronic Fatigue Syndrome which is a metabolic disorder. I’ve been tested and my body switches from aerobic to a anaerobic metabolism at 78 bpm. So I quickly run out of ATP and my body creates lactic acid which causes pain. I have to manage my activity to stay within my aerobic threshold, but even that doesn’t really help. Because of this I can be active for only very short intervals before I have to rest. I am fully disabled. If I do too much, like try to cook a meal, my muscles freeze up and stay that way for days; stiff, very weak and sore. Thinking, loud noises, conversations and other sensory stimulation all use energy and have to be limited. I literally can’t move and think at the same time. This is a great illustration of the processes involved.🌻😊

That was an incredible explanation. I rarely have understood biochemistry in the past; it has always been too confusing. You managed to suspend that block with your visuals and analogy. Thank you!

Never thought this can be explained in such an eaey to understand manner. Thank you so much.

Amazing video! For my biology class we have to learn this and I was so lost. Coming across this video helped me understand and kept me entertained with the drawings and great examples. Thank You!!!

Legend, love the grand tour reference with captain slow. Subbed

Really good visuals and explanation! It is so much clearer than what the textbook had explained. Thank you for your work!

I have watched many videos on this and this is absolutely the best video yet. Thank you so much

Up to the mark, perfect explanation!

Best video I've seen so far teaching the difference between aerobic and anaerobic. Great Job! :) Subbed

Thanks so much I was totally lost on this subject until I watched this video

Love the demonstration on this video. I will now have the mental images of these engines stuck in my head. However, I will like to note that you are missing one of the very important energy systems we use in the phosphagen system. Thanks for the video!

Great explanation! But I must mention a few things that are missing (in my opinion). The energy production role of fatty acids in blood and in muscle tissues. In this video it's not present at all. And that lactic acid can be converted to glucose by liver to give another wave of energy.

I already knew a lot about this topic as I am a personal trainer but you’ve managed to make such an awesome video that I learnt a lot still

Grand Tour is awesome! One of my favorite shows too. I like how you related this to it

This is a very effective 9-minute explanation about a complex thing. Thank you for making this video and sharing it...

As a nurse, I've taken biology, microbiology, and pathophysiology (now for a 2nd time as a MSN student). This is the first time I've understood this process. Thank you!!! This was really helpful!

You have amazing content. Really glad i found this channel

Perfect video! I was looking for that from a long time!

This is one of the best explanation I ever heard of!!!

Omg, I love you for loving the grand tour, definitely subscribing :)

This video is just like a movie that doesnt make sense until the last piece is revealed. It totally makes sense when you watch it till the end. Wonderful presentation for a complicated topic. But you made it easy to understand! Thank you

Very well explained. It made perfect sense. The car and generators were good addition to the video. Many channels just draw molecules and atoms and it can get complicated since you have to remember the role of each of them and what is their relation to each other. Car, battery and generators are simplifying it well, everyone knows their role and relation to one another.

Amazing video really helpful

Am in love with that video by giving that marvelous example to break the concept to be understood in a very easy way THANK YOU, nice work guys keep going.

This was a brilliant explanation, the kind that you remember completely

THANK YOU! You took a complex subject and gave me greater understanding!

It would be so disloyal of me if I don't appreciate this great content.

Literally any part of the body ATP: I come from there

Love it! Can you do a follow up on just training on a keto diet? What do we start with to use for fuel??

I thought the analogy of the process would seem like a normal internal combustion engine, this is great explanation! Thank you. This simple logic makes the obligation of breathing control when working out make sense

Super really easy to understand as i am going to take exercise physiology on my final exam. Really helpful. Thanks!

Man you are amazing. You delivered so much in less time. Great video ♥️

What a beautiful presentation.......so perfectly and logically explained. Thank you.

Dude this video is so complete, thank you very much!!!

This is a brilliant high-level explanation of these processes. Thank you!!

Well done, great analogy and a very well-paced video.

So perfect!!! THANK YOU!!!

Great analogy and explanation! Thanks!

Your awesome! Thanks for an amazing video!

Holy shit...Your a genius! Wow this is actually making sense, I couldn't get some of the details regarding respiration but you nailed it! Thank you!!!

This video almost had me crying, I finally understand now!!!! Thank you!!!!

Thanks. Great video to learn a bid more about IMPORTANT stuff

This is an amazing video. I like the way it is presented with a background music.

You have no idea of how much this has helped me on my essay Keep up the good work and thank you !

Thank you Dorian! I’m back to distance running vs speed!

Nice illustrations. Thanks for sharing your work.

Thank you you for the amazing explanation..

Simple and straight to the point explanation ! Thanks

huge respect , thank you so much!

This was an Excellent(!!!) explanation. If I may, I'd like to ask a, or a few questions. I've been doing CO2 Tables (from free diving) to increase my CO2 tolerance. I've noticed that I've gone from mouth breathing at a heart rate of about 165 bpm to being able to maintain fairly comfortable nasal breathing at a heart rate of 180 bpm. My understanding is that having higher levels (and tolerating higher levels...) of CO2 in the blood stream can buffer hydrogen ions and lower blood lactate levels. Now, common sense says that if you're able to breath through your nose fine or even somewhat strained, then your body has enough oxygen to be more aerobic. But, I want to know if that is actually true. If I'm maintaining nasal breathing only at a heart rate of 180 bmp, then do I actually have enough oxygen to produce ATP via Krebs cycle and electron transport chain, or am I just tolerating the discomfort of higher levels of CO2 and still predominately using Glycolysis? In a nutshell, what is my dominant energy system (aerobic or anaerobic) if I am nasal breathing fairly comfortably at such a high heart rate? I keep being told that my breathing is a signal of the state my body is in. Thanks!!!! J

Really great video and easy to understand explanation, thank you for making this video!

Ma shaa Allah this is helping. thank you God bless you😊

Amazing!!!!!! Concise.Great.

This videos is amazing! Perfectly explained I love learning more about exercisie physio! :)

This is just perfect. I really don't need to watch a second video. Keep up

Good video that really came together at the end. My only critique is that it was not clear what was going on until the end, but then it did come together in a nice way.

Epic. Thank you

Great video. Thank you!

I understand now! Thanks!

Thank you very kindly ❤️

Best explanation on KZfaq

This is really helpful!!!! Thanks!!

I’d like to know how to create a specific training program to optimize energy creation using all 3 systems at once

YES MY MAN WATCHES THE GRAND TOUR IM SUBBING

This was absolutely amazing for basic overview . As you said towards the end, it's a complicated topic so student should really take the time out to learn the finer details.

Great video!! Thank you! But what about the ATP-PC System and the beta-oxidation of the fatty acids?

Best way your explain one hour m trying to understand what all these thing is .. your in 8 min make me understand god bless yours

Great information!! Thanks Dorian

Wow! Just Awesome!👍👌

This is a great summary of the physiology behind how our cardiovascular system actually influences our performance. Wish I had this insight long ago.

Concise & good explanation! Keep it up!

Wow. Thanks for that simple take on a complicated topic

This makes so much sense !

I enjoy this one very much! Thanks for sharing.

Traditionally we are taught there are three energy systems: 1. ATP-CP, 2. Anaerobic Glycolysis, 3. Oxidative (beta oxidation and aerobic glycolysis) how does phospagen and beta oxidation play into your metaphor? And do the Kreb’s Cycle and ETC fall under Anaerobic Glycolysis? Thoroughly enjoy your channel hopefully you settle the confusion of “three energy systems”

Thank you, I understood it perfectly.

Lol, when this video started, I shouted ATP AND KREBS CYCLE. Truuuue. I figured this out one day during a hiit workout. I was in microbio classes at the time, and I suddenly understood why and how hiit workouts worked. Biology is cool.

Thank you!

wow this information is good, keep it ups bro
