The chemical which regulates the enzymatic activity is:
Correct answer: D. Both A and B
- A. Activator
- B. Inhibitor
- C. Substrate
- D. Both A and B
Explanation
Enzymes can be regulated by other molecules that either increase or reduce their activity. Molecules that increase the activity of an enzyme are called activators, while molecules that decrease the activity of an enzyme are called inhibitors.

About Enzyme Inhibitors
Enzyme inhibitors reduce reaction rate by interfering with enzyme-substrate interaction or catalytic activity. Coverage includes reversible competitive, non-competitive and uncompetitive inhibition, the effects of inhibitor concentration on reaction rate, and why competitive inhibition can be reduced by increasing substrate concentration.
