Question

Q) Which molecule binds to the active site of an enzyme.
(a) Allosteric activator
(b)Allosteric inhibitor
(c)Non-compititive inhibitor
(d) Competitive inhibitor

Answer 1

Explanation:

substrates

Enzyme Active Site and Substrate Specificity

The chemical reactants to which an enzyme binds are the enzyme's substrates . There may be one or more substrates, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products.

Answer 2

(d) Competitive inhibitor binds to active site of an enzyme.

• Active site of an enzyme is the most part where substrate binds. Here chemical reaction takes place which transforms the substrate changes to product.
• Inhibitors bind to active site or allosteric site hindering the conversion of substrate to product. There are various types of inhibitor.
• Competitive inhibitor competes with substrate to bind at active site.
