How do protein kinases affect enzymes?

  • A. They add a phosphate group (phosphorylation) to the enzyme.
  • B. They increase the release of an enzyme.
  • C. They break down the enzyme.
  • D. They increase the secretion of an enzyme.
Correct Answer: A

Rationale: Correct Answer: A

Rationale:
1. Protein kinases add a phosphate group to enzymes through phosphorylation.
2. Phosphorylation alters enzyme activity and can activate or deactivate enzymes.
3. This process regulates enzyme function and signaling pathways.

Summary of other choices:
B. Incorrect - Protein kinases do not increase enzyme release; they modify enzyme activity.
C. Incorrect - Protein kinases do not break down enzymes; they regulate their activity.
D. Incorrect - Protein kinases do not increase enzyme secretion; they modify enzyme function through phosphorylation.
