    It is really really good explanation even for PhD students. Thank you so much. You know... the more you know about a topic, the more comfortable with it. This is exactly your situation. Thanks again...

    You are really beyond my lecturers I hope that maybe I will pass anatomy and physiology bcz of AK Lectures.
    I wish every University Lecturers should be like you, students can be get quality knowledge.

    you have been the only video i have watched on the sliding filament theory that actually explained to me ho the calcium got onto the troponin
    thanks

    Been watching your videos for this entire semester we've had of biochemistry and I've always left your videos a tonne smarter than when I came. No matter if it's anabolism, catabolism, muscle contraction, biochemical methods, the electron transport chain or reactive oxygen species, you never cease to impress; your videos are made in such a nice, digestible way and are incredibly informative and always on point! Thanks a lot for all your help, I wish you the best! :-)

    Do steps 3 and 6 repeat many times so that thin filaments from each side move towards each other and eventually close up the gap and overlap on each other at the end of contraction phase?

    I have a question! When you release the ADP+ Pi in step 4, where does it go? Does it bind onto the actin in an ATP shape?

    • @georgeklucsarjr1988
      @georgeklucsarjr1988 4 роки тому

      It's been 2 yrs, so I hope you found your answer. If not, do you think it makes its way back to the mitochondria to be reformed into ATP ( through the electron transport chain )? Probably
