  • good explanation but u could have used a better diagram not a really weird biochem diagram it looks confusing lol

  • Sexy

  • beautifully explained..thankyou..:)

    

  • @passikg his other videos cover that

  • I think this video is very superficial...doesn´t cover what I hoped for. Like Ca2+ Ions stimulate everything and all that.

  • STANDARD

  • really good explanation but im just bad at science & i still sort of don't get it =\ but i understand all of your math videos so still thumbs up to you sir ! :3

  • PLEASE make a video just for enzymes

  • Dude great video, cant believe I have just learned in a 9.38 min video what I have been trying to learn from reading books in days. Cheers mate.

  • I wouldn't understand anything of what my Bio Professor is trying to "teach me" without your help in this video - definitely sharing this with all the classmates I have so that we actually UNDERSTAND for once. Thanks so much!!

  • you just saved my chances of passing my exams!! thanks

  • You saved my life, again. Thanks !

  • I appreciate this video and your efforts to teach. However, energy is never released when bonds are broken. Bond breaking is an endothermic process, therefore the breaking of the adenine-phosphate bond requires energy. The only reason we see that energy release is that the overall energy input/out results in a higher output. Again, thanks for the lessons.

  • @ankit383 grow up >.<

  • Wow, I wish I had just watched this video instead of going to class today.

  • Thank you so much! I have a college exam tomorrow and this made everything so much clearer! THANK YOU THANK YOU THANK YOU! No one else explains it completely and slow enough to understand along with writing it down so things are clear. THANK YOU!

  • totally understand, very enjoy for your explaining ,thank u so much

  • Love how you simplify the topic my putting into simple steps.

  • Well done Khan!...LOVE the way you teach this. I appreciate you writing out EVERY letter...this shows me step by step what you're thinking and doing. I learn best this way. Keep doing it this way- Don't change a thing- everyone else loves it.

  • No doubt you have the knowledge but maybe next time have prepared text so that so much time does not go by while you write out every letter..

    Otherwise Thanks.

  • @CherryPi420

    #1--the guy has almost 2,000 videos a free information so maybe he doesn't have time to script everything perfectly

    #2--people need time to absorb ideas, process them and put them in our memory. If everything was written out this video would be like 2 minutes and you'd have to watch it like 10 times to absorb it.

  • thank you--wish i had seen this last year.

  • thank you so much for all the help......I didn't know where to start and where to finish up until last night I watch the entire video on membrane transport...thank you thank you. your a great teacher!!
