1.If the supply of ATP to a shortening muscle is completelydepleted, what will happen to the cross-bridge cycle? What is thename if the phenomenon that results from complet ATP depletion?
2.Order the following 10 events that summarize musclecontraction. Remember that a muscle contraction begins with thetransmission of a nerve impulse to a muscle fiber
a. the power stroke
b. Opening of ryanodine Ca2+ channels in the sarcoplasmicreticulum
c. Binding of mysosin cross-bridges to actin
d. release of acetylcholine into the neuromuscular junction
e. confromational change in tropomyosin troponin complex
f. binding of ca2+ to troponin
g. binding of atp to myosin cross-brisges
h. depolarization of the muscle fiber
i. hydrolysis of atp bound to myosin cross-bridges
j. action potential propagation along the transverse tubules
