Cyclin-dependent kinases (Cdk's) catalyze the phosphorylation of targeted proteins, a process that
A) decreases the mass of the protein.
B) makes the targeted proteins hydrophobic.
C) changes the shape and function of the targeted proteins.
D) gives the proteins a three-dimensional shape.
E) blocks the cell cycle from proceeding.

Question

Quizplus · Accepted Answer

Cyclin-dependent kinases catalyze the phosphorylation of targeted proteins, which changes the shape and function of the targeted proteins. This can activate or deactivate the protein and regulate various cellular processes, including the cell cycle.
