What is the role of ATP in the sliding filament theory?
A)Energizes the myosin cross-bridge
B)Breaks the link between actin and myosin
C)Both energizes the myosin cross-bridge and breaks the link between actin and myosin.

Question

Quizplus · Accepted Answer

ATP plays a crucial role in the sliding filament theory by energizing the myosin cross-bridge, allowing it to bind to actin and generate force. It also breaks the link between actin and myosin after the power stroke, allowing the cross-bridge to detach and prepare for another cycle of ATP hydrolysis and force generation. Therefore, both A and B are correct, making C the best choice.
