During one cross-bridging cycle in striated muscle one ATP molecule is hydrolyzed. Explain the two times when the energy from this hydrolysis is used, and what “work” is done in each case.
The ATP hydrolysis releases energy with yielding adenosine diphosphate (ADP) and inorganic phosphate. ATP hydrolysis releases energy, that changes the angle of the myosin head into a “cocked” position.
