Problem:
How does the hydrolysis of ATP(to ADP+P) after the proteins in a muscle cell to allow for contraction?
A) Hydrolysis results in activation of myosin to the extended position
B) Hydrolysis results in activation of myosin to the flexed(bent) position
C) Hydrolysis results in the movement of tropomyosin so that actin active sites are revealed
D) Hydrolysis results in the breakage of cross bridges between actin and myosin
Please explain
