Allosteric enzymes
Correct answer: B. Have multiple subunits and regulatory sites
- A. Follow Michaelis-Menten kinetics strictly
- B. Have multiple subunits and regulatory sites
- C. Are not affected by feedback inhibition
- D. Always show competitive inhibition
Explanation
Allosteric enzymes have multiple subunits with regulatory (allosteric) sites where activators or inhibitors bind, affecting enzyme conformation.

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.
