Cyclin-dependent protein kinases can regulate the progression of cells through the cell cycle by phosphorylation of proteins such as:
A)insulin.
B)myoglobin.
C)myosin.
D)retinal rod and cone proteins.
E)All of the above

Question

Quizplus · Accepted Answer

Cyclin-dependent protein kinases (CDKs) specifically phosphorylate proteins involved in cell cycle regulation, such as cyclins and certain checkpoint proteins. Insulin, myoglobin, and retinal rod and cone proteins are not directly involved in cell cycle regulation, whereas myosin is involved in cellular contraction and not the cell cycle. Therefore, the best choice is C, myosin.
