Match each perturbation of the skeletal muscle contraction cycle with the consequences it would cause. Each answer can be used only once.

___ Remove all ATP from the muscle fiber.

___ Mutate myosin so that it would not be able to hydrolyze ATP and produce Pi or ADP

___ Deplete muscle cells of intracellular calcium

MATCH WITH THE FOLLOWING OPTIONS:

A. Actin would remain bound to myosin, the rigor state would be maintained.

B. Myosin would be able to release actin, but would not be able to rebind to actin to form a weak cross-bridge

C. Tropomyosin would block actin-myosin binding site, power stroke would not occur
