Allosteric enzymes have _ major site(s).
Correct answer: B. 2
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
Allosteric enzymes have, in addition to their active site for substrate binding, another site called the allosteric site. At this site, a molecule other than the substrate can bind. This binding regulates the enzyme's activity by either enhancing or inhibiting its action.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
