Should be called the complicated system

I got through Pre Med because of you. Sometimes your lectures were too advanced for me and I thought "I will probably need these when I'm in medical school." 5 years later and I will get through medical school because of you. Thanks man. I hope someone is paying you very well out there.

i love the way you stress on words it helps me stay focused.. ;) you are born a teacher ,keep up the good work

In respect to the C4bC2b complex, for about 5 years or so in the recent past, immunology textbook writers wanted to make the process more uniform since C2a is the only large factor which remains associated with the cell surface and renamed it C2b to be more inline with C4b. So C4bC2b was published for a couple of years but it never really stuck as C4bC2a was already widely accepted and established.

Fragment b is always kept and Fragment a is thrown into the plasma, but there is one exception, it's for C2. So instead of keeping C2b , you keep C2a instead.

clearest explanations on youtube. Much better than a certain "academy"

You helped me to pass the oral exam in Biochemistry in Step1. My professor asked me the questions you underlined in your videos and it would normally required me to read thick text books to understand. Now you are helping me to pass Immunology. I can't thank you enough.

This was SO helpful - You are making such a difference for me. I am almost crying of hapiness

Hi! I'm from Brazil, I'm Pharmacy student, and I must say u r an incredible teacher! Your classes help me a lot! Thanks for Everything!

Amazing summarized lecture on the classical complement pathway and its significant immunological functions! Thank you so much for this, sir!

Thank you. You saved my life today!! I needed to teach the Complement System to my students and this explained it so well. THANK YOU!!!!

I just want to say ive watched this guys videos since grad school immunology. I am now in medical school, and still use his videos on all go his topics. 10/10 would reccomend AK Lectures!!

you made me understand in less than 15 minutes what my professor couldn't make me understand in more than 2 hours. thanks a lot :)

Everything is simplified and understandable. I am so thankful for your style and form of lectures.

Excellent Video! Clarity is second to none. Brilliant

You are the best and i guess the only one on youtube who really deeply understand the scientific material and introduce it with no side talk and in a very simple and informative method Best regards to your efforts

Your lectures are amazingly easy to understand. I'm so grateful for your effort.

Love how you make everything easy, you’re the best 👌🏻keep up the good work.

He’s so good at explaining. I can’t do this even if I have perfect understanding of something.

"Clocked" couldn't figure this shit out for months!

Master of all, i almost use half of time before exam watching your so organized precise articulately presented lectures. Love and pray for you from bangladesh.

this was honestly so helpful! thank you for being so clear in you explanation

I love this man so much right now

love your accent 😍😍😍 ,the way you speak 😘😘 understandable

Thank you so much! This video really helped me understand the classical pathway of the complement system.

You're helping me so much in my Immunology and Clinical Chemistry subjects. Thanks a lot! :)

Thank you so much for making this video, I found your explanations really clear and helpful!

Thank you for this video! You explained this way better than my patho book.

your youtube channel is the 1st one that helps me a lot in my studies....solute you

Hi I noticed that the C3 convertase should be C4bC2a ☺️ I looked it up in Immunology 7th Ed David Male page 90 fig. 4.4 ☺️

Amazing, very easy to follow. Thank you for sharing

classical pathway made simple and sweet..... great video

i hope you know that till this time while im in training for speciality i still return to your videos to remember things 🙏 may God bless you wherever you are 🙏

you're absolutely great and talented, thank you for these insightful videos, really help me to understand the materials in my college :) may God bless and keep you

I like how you started with the big picture first and then went into the nitty gritty details. My immunology prof doesn't do that enough, hence why I'm here. She will drill the process steps, but doesn't really get at the purpose of why these things happen. Thanks for this. :)

I love u man u are the best lecturer i have seen ❤️❤️❤️❤️❤️

Somehow you can make me understand those topics so easily. Thank you

Your lectures are worth to be acknowledged on my final dessertation

Great teacher, great explanations!

quality of this video cured my cancer via my innate immunity boost

10:03 shows just the info. Fairly simple to follow what he's written. Much better explanation than my books.

Really, I appreciate these courses

What a Man,Good stuff..Life saver

i love this man makes every make sense

I had difficulty in understanding complement system but with this video I will teach complement system to my friends. thanks as much as sea :-)

Hats off sir, you are better than my lecturer. Remain blessed.

Hello AK lecture, according to my professor, C4bC2a is the C3 convertase that cleaves C3 to C3a and C3b. And also C4bC2aC3b is the C5 convertase and C3 convertase cannot cleave C5. Please keep on making video. thank you very much.

Hi, This is amazing! Great Job! I use this to teach my students and it is really really really good!

You helped me a lot. Inmunology final tomorrow. Wish me luck.

AMAZING!!!!! You are the best explainer

glad that many realise whats in c3. overall, this video is helpful in my Immunology subject. worth the subscription.

Thanks so much for this... You are appreciated.

thank you for the helpful videos much appreciated.

Amazing. Thank you!

Shouldn't the C3 Convertase be C4b2a, instead of C4b2b?

Sir, great explanation, I'm grateful 👏

This guy helped me pass my doctoral exams 🤲🤲

More thanks again for your help sir keep it up ,by abel kakinda from Tanzania at CUHAS.

There is Super man, there is Batman, there are the X man, there are all kind of super heroes and then there is you... the one who saves me every single time since I started Biomedical sciences.

Many Thanks from the UK🎖️🎖️🎖️

best video ive ever seen on this

I love your recaps at the end of your videos. Great video!

I'm so thankful for your efforts ☺️☺️☺️

Thanks a lot for this lecture sir..... Your notes and explaining is legendary..... Keep up the good work sir

Thanks for the video....greetings from Brazil

Thanks a lot for your explanation

Woowoo.. you make it so easy and helped me with my exam..thank you alot.

these notes are wonderful

Very well explained! thank you very much 😊

Love from Indian occupied kashmir..... awesome way of reaching

Awesome! Thank you!

I am really grateful for these lessons that you are lecturing, but I've got a small note which I hope you will consider, you're speaking with such loud tone and keep speaking without any pause to take a breath. anyway your lectures are very useful for me, thanks

What a way of teaching.. Superb #AK

Great one👌👌👌...n thanks to A K Lecturers fo adding new stuff in C3 convertase part(c2b c4b)...it is nt at all mentiond in books till now, thnks again...😊😊😊

C4b2b is correct and it's the new form of formerly known C4b2a complex aka C3 convertase. Anyways, the name changed cause of some wrong nomenclature of complement proteins. The 'b' in these complexes stand for binding and 'a' stands for anaphylotoxins, so that should be it.

Very useful!! Thank you :)

Very helpful!

hello, in the classical pathway in my powerpoint lecture it says that c2a binds with c4b but in your lecture it is c2b and c4b, is my book wrong?

Wow, this was amazing! Thank you so much! #thumbsup

Great video! Very clear, thank you so much for posting. I do have one question though. When mentioning the C3 convertase you said that it is formed by a C4b and C2b molecule. However, in my text, as well as from my professor, I have been told that it is composed of a C4b and C2a, instead of C2b, molecule. I was wondering if there are any discrepancies in naming of the subpart of complement molecules after they are cleaved, or if this was just a small mistake? I apologize for the specificity and detail of my question, I just want to ensure I am understanding this process correctly. Thank you kindly, Kat

Thank you. This helped a lot :)

thank U man thank U that was so efficient for me

Thank you sir it was very helpful.
