  1. there’s a coenzyme Q within complex 3? how many coenzyme Q’s are in the electron transport chain…? is the coenzyme Q that takes up electrons from complex 1 the same that takes up electrons from complex 2?

  2. You don't have any idea how much this video helps me to understand the q cycle. I didnt find any video about this topic in spanish (i'm from south america).
    Thank you so much.

  3. This was a great explanation. I'm taking biochemistry and had trouble conceptualizing how you could get 4 protons from 2 electrons. The way you've drawn the process clearly shows how the second electron in each transfer is recycled back in. I hope to find time to look through other videos. At the very least I'll send a link to other struggling students.

  4. Plz explain the flow of protons from complex 3 and 4 again. I am bit confused that finally how many protons pump by complex 3 and 4 in intermembrane space.
