• A. Substrate
• B. Product
• C. Catalytic site of the enzyme
• D. Non-catalytic site of the enzyme

Answer 1

Answer: (D)

Non-catalytic site of the enzyme

Allosteric regulation is the regulation of an enzyme by binding an effector molecule at a site other than the enzyme's active site. That is, it binds to the non-catalytic site of the enzyme. The site to which the effector binds is termed as an allosteric site.

So, the correct answer is option D.
