Muscle Contraction: ATP, Actin, Myosin
Вставка
- Опубліковано 2 жов 2024
- In this video we will discuss the mechanism of muscle contraction, which is initiated by tropomyosin moving and exposing the binding sites for myosin on the actin filament. This further allows a cross-bridge to be formed in between the myosin and actin filaments.Calcium binds to troponin and tropomyosin slides from the actin filaments’ binding site allowing the heads of myosin to bind to the actin’s active sites hence forming a cross-bridge.

Um I honestly feel like you made me more confused than when I came
:( was hoping for actin and myosin contraction but thanks anyways
thank you. one thought. is this also a wedding dress code tutorial?
this would be a great review,, but not an explanation... Too fast to pick up the first time... the music is nice but it makes everything feel rushed. Thanks for the info though.
Not helpful
👍👍 thnx from morocco
merci tu rhalass
I am in love with you 😍
