The specific region of an enzyme to which the substrate binds and where catalysis occurs is called the
Correct answer: B. active site
- A. allosteric site
- B. active site
- C. cofactor site
- D. regulatory site
Explanation
The active site is a cleft formed by the folding of the chain, whose shape and chemistry fit the substrate. Allosteric sites are separate locations where regulators bind, so a question about the substrate's own binding place points only to the active site.

About Characteristics of Enzymes
Enzymes are globular biological catalysts that lower activation energy without being consumed, usually showing specificity for particular substrates. Questions cover active sites, enzyme substrate complexes, the lock and key and induced fit models, intracellular and extracellular action, and the effects of denaturation, while distinguishing enzymes from non biological catalysts.
