Myosin phosphatase
A) activates myosin kinase.
B) forms the cross-bridge.
C) removes phosphate from myosin.
D) binds to calcium-calmodulin complex.
E) opens Ca2+-channels.
Myosin Phosphatase
An enzyme that dephosphorylates myosin light chains, which plays a crucial role in muscle relaxation and cell motility.
Myosin Kinase
An enzyme that catalyzes the phosphorylation of myosin, a process crucial for muscle contraction and regulation.
Cross-bridge
The connection formed between the heads of myosin filaments and actin filaments during muscle contraction.

Final Answer :
C
Explanation :
Myosin phosphatase is an enzyme that specifically removes phosphate groups from myosin light chains, which is crucial for muscle relaxation by reversing the phosphorylation that is necessary for myosin to interact with actin and generate muscle contraction.
