Question

which of the following shows atpase
activity during muscle contraction​

Answer 1

Answer:

Myosin ATPase is an enzyme with ATP phosphohydrolase (actin-translocating). This enzyme catalyses the following chemical reaction: ATP + H

2

​

O = ADP + phosphate.

ATP hydrolysis provides energy for actomyosin contraction. Myosin is not only an actin-binding protein, but it is also an ATPase.

Myosin has ATP-dependent motor proteins that help in muscle contraction. They are responsible for actin-based motility.

Answer 2

Answer:

I guess...

Explanation:

During muscular contraction myosin cross bridges heads. Myosin is not only an actin binding protein. It is also an ATPase (an enzyme) which is activated by Ca2+ and Mg2+ ions. Hence, ATPase enzyme is located in myosin.
