Question 2

What is happening during the latent period of a muscle twitch?

Accepted Answer

A)  The muscle relaxes and returns to its former length. 
B)  Fresh ATP binds to the myosin causing it to return to its resting position. 
C)  ADP and phosphate are released, and the power stroke of the contraction occurs.
