How does the hydrolysis of ATP (to ADP+P) alter proteins in a muscle cell to allow for contraction?
A) Hydrolysis results in activation of myosin to the extended “ready” 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.
Homework Answers
Option A is correct
Hydrolysis results in activation of myosin to the extended ready position which is called cocked position

5. (4pts) A. Referring to the cross-bridge cycle in muscle contraction, please match the following changes in myosin binding state to events in the ATP hydrolysis and exchange cycle: Myosin conformation and actin-binding state The myosin motor moves towards the plus end (energized") and binds weakly to actin. Power stroke - Myosin binds tightly to actin, moves to a "rigor" position, & pulls actin. Myosin releases from actin. ATP hydrolysis cycle in myosin a. ATP becomes bound b. ATP hydrolyzes...
