Question 1

The tension generated in a skeletal muscle fiber is directly proportional to the number of
◦ nebulin and titin molecules present.
◦ high-force crossbridges formed.
◦ active sarcomeres.
◦ thick and thin filaments present.
◦ low-force crossbridges formed.

Question 2

When a skeletal muscle cell contracts and the muscle shortens,
◦ myosin heads generate a single power stroke.
◦ the actin ATPase allows the actin molecule to swivel.
◦ the position of an actin molecule relative to a myosin molecule does not change.
◦ the actin molecule swivels during the power stroke.
◦ some myosin heads are forming crossbridges as others are releasing them.
