Biochemical evidence supporting our current model of muscle contraction includes the observation that
A)myosin binds calcium.
B)titin binds calcium.
C)actin has ATPase activity.

E)actin and myosin have the same molecular weight.

Question

Quizplus · Accepted Answer

Myosin has ATPase activity, which is an important step in muscle contraction. ATP hydrolysis by myosin provides the energy for the myosin head to attach to actin, pivot, and generate force. This supports our current model of muscle contraction.
