Q

Muscle Contraction Step 1

Q

Muscle Contraction Step 2

A

Myosin head is attracted to the active actin site. Contact causes reflexive contraction until ATPase (cone - Mg) cleaves a phosphate off the ATP. Myosin is then released from the active actin site. Myosin head will grab next site if available.
