What happens at the level of the muscle proteins during muscle contraction is that the myosin-binding sites are exposed, and due to insufficient ATP present, myosin binds to actin to begin cross-bridge cycling.
<h3>What is muscle contraction?</h3>
Muscle contraction is defined as the activation of tension-generating sites within muscle cells.
During muscle contraction, the myosin-binding sites are exposed, and due to insufficient ATP present, myosin binds to actin to begin cross-bridge cycling.
Also, as the muscle contracts, thick filaments shortens and thin filaments slides.
Thus, what happens at the level of the muscle proteins during muscle contraction is that the myosin-binding sites are exposed, and due to insufficient ATP present, myosin binds to actin to begin cross-bridge cycling.
