Great easy to understand explanations. Your videos are a like a hidden gold nugget for people preparing for the new MCAT which is heavily biochem based! Thanks alot
Thank you so much! Your videos earned me an A in Metabolic Biochem in school and now I'm rewatching them 3 years later as I study for the MCAT. Your videos are so clear and straightforward compared to dense textbooks. Thank you!
SWEEEEEEEEEEEET! I'm glad you got that A, and I'm glad you've come back to watch the videos again. Here's to you rockin' your MCAT! Cheers, and happy studying! :]
Fantastic job!! I am a big fan of your videos. I recreate your drawings into my own personalized one sheets. Your Michaelis Menten Kinetics video helped me perform well on my exam last quarter. Thank you for the simple language and translating some tough concepts. You're a huge help to many other medical students--thanks a million! Thank you, thank you! :)
Sorry for the late reply, but the reason for that is because it is considered that the Succinate Dehydrogenase enzyme is on the mitochondrial matrix side of the inner mitochondrial membrane, especially since it is involved in the TCA/Krebs/Citric Acid Cycle.
zeromethanez An iron-sulfer cluster in complex II grabs the electrons from FADH2 and gives those electrons to Coenzyme Q. This is shown and explained a bit in Electron Transport Chain (Part 2 of 3) - Complexes starting at 12:35.
+beverly ejiofor the reaction is: QH2 + 2CytC + 2 H+ --> Q + 2CytC + 4H+ where the first CytC is oxidised, the second reduced. the first 2H+ are in the matrix, the latter 4H+ in the IMS

your videos are brilliant - better than my lecturer! x
Indeed, the process is awsome. So are YOU. Thanksss a lot

Thank you so much for these helpful videos!
Unreal videos...such a great help. Thank you very much!
Gabby C Thanks! :] Sure thing!
You are awesome man! Thank you and keep it up!
thank you very much for your activity
OMGGG THANKSSS too much........studying for my midterm in one week ..the diagrams in my book are so confusing!!!!!
You are awesome ,, I always study through your videos .
Can you explane the glyoxylate Cycle ?
Dude thank you so much !!
The best. thank you
Wonderful lecture dear sir
thank you sir!
Thank you :D
Good videos
Does Q carry 2 electrons from complex I & II?
Thank You!
Ali H You're welcome!
please why there is in some books that complex 2 is not incorporate in inner mito. membrane?
Sorry for the late reply, but the reason for that is because it is considered that the Succinate Dehydrogenase enzyme is on the mitochondrial matrix side of the inner mitochondrial membrane, especially since it is involved in the TCA/Krebs/Citric Acid Cycle.
isn't it 4H+ from complex I, 2H+ from complex III, and 4H+ from complex IV?
Thanks
Cheo97 Sure thing!
How does FADH2 get oxidised at complex 2?

yassssssss
Doesn't complex 3 pump 2 H+ protons not 4+?
+beverly ejiofor the reaction is:
QH2 + 2CytC + 2 H+ --> Q + 2CytC + 4H+
where the first CytC is oxidised, the second reduced. the first 2H+ are in the matrix, the latter 4H+ in the IMS
+beverly ejiofor i.e. the complex "takes" 2H+ from the QH2, leaving a Q as the product, maybe thats where your error is?
2H+ 1/2 O2 ----> H4O
Fucking amazing.
Jesper Johannesson Hahahaha! That's what I like to hear!
i love you
ben de seni.....
Thanks, that was very helpful but I think complex 2 also pumps H but into the matrix.
