If molecule can bind to another site of the enzyme rather than the true active site, it is referred as _:

Correct answer: A. Non-competitive inhibitors

  • A. Non-competitive inhibitors
  • B. Allosteric inhibition
  • C. Competitive inhibitors
  • D. Irreversible inhibition

Explanation

The correct answer is Non-competitive inhibitors. These inhibitors bind to an enzyme at a site other than the active site, causing a conformational change that reduces enzyme activity. Unlike competitive inhibitors, non-competitive inhibitors do not compete with the substrate for the active site. Allosteric inhibition is also a form of non-competitive inhibition but refers specifically to binding at an allosteric site which is a regulatory site. Competitive inhibitors bind to the active site, directly competing with the substrate and do not bind to other sites. Irreversible inhibition involves covalent binding that permanently inactivates the enzyme, which is not the case described in the question.

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.
