If ATP was present that could not be split into ADP and , at what step will myofibril function be stopped?
a. Myosin molecules will be unable to assemble into thick filaments.
b. Myosin heads will bind to the actin filaments, but the power stroke will not occur and actin filaments will not slide over the myosin filaments.
c. Myosin heads will be unable to bind to the actin filaments. d. There will be no block in the cycle, since ATP hydrolysis is not required for this process.
e. The myosin heads will remain attached to the actin filaments after the power stroke.
