Binding site for myosin to shorten sarcomere
WebJan 29, 2024 · Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. What is the purpose of the sarcomere? The main function of the sarcomere is to allow a muscle cell to contract. WebAn individual sarcomere contains many parallel actin (thin) and myosin ... The interaction off myosin and actin proteins is per the core of you current understanding off sarcomere shortening.
