Problem 2: Enzymes for Regulation
ans:
A. proteases
Incorrect.
Proteases degrade proteins. One example, trypsin, is important for digestion
B. transferases
Incorrect.
Transferases are enzymes that transfer molecules.
C. kinases
Correct.
Yes, kinases add phosphate to molecules, and the modification can serve as a "switch" to turn events in the cell on or off. Cdk or cyclin dependent kinases regulate the cell cycle.
D. nucleases
Incorrect.
Nucleases are classes of enzymes that degrade nucleic acids.
