Allosteric enzymes have _ major sites.
Correct answer: B. 2
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
Allosteric enzymes have two major sites:1. Active site where the substrate binds and the chemical reaction takes place2. Allosteric site - where an allosteric regulator (activator or inhibitor) binds to change the enzyme's activity.3. These sites allow the enzyme to be regulated and respond to the needs of the cell.

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.
