The contraction of skeletal muscles is based on
A)actin filaments coiling up to become shorter.
B)myosin filaments coiling up to become shorter.
C)actin cross-bridges binding to myosin and transitioning from a high-energy to a low-energy state.
D)myosin cross-bridges binding to actin and transitioning from a high-energy to a low-energy state.

Question

Quizplus · Accepted Answer

The contraction of skeletal muscles is based on myosin cross-bridges binding to actin and transitioning from a high-energy to a low-energy state. This causes the actin filaments to slide over the myosin filaments, resulting in muscle contraction.
