Answer:
The options
A. Methylation
B. Dephosphorylation
C. Phosphorylation
D. Enzymatic transformation
The CORRECT ANSWER IS B.
B. Dephosphorylation
Explanation:
The regulation of the phosphorylation of myosin light chain (MLC) is a major step in the regulation of smooth muscle cell contraction.
The dephosphorylation of myosin light chain (MLC) occurs in smooth muscle tissue and causes the relaxation phase of the muscle cells. This step is controlled by the MLC phosphatase (MLCP).
