Question

In a chemical reaction, the location on an enzyme in which the substrate binds to the enzyme is known as which of these?

• A. Catalyst
• B. Allosteric site
• C. Product
• D. Active site
• E. Substrate

Answer 1

The correct option is D Active site

A. Catalyst is a substance or a molecule that increases the rate of reaction i.e. catalyze the reaction but itself is not involved in the reaction.

B. Allosteric site is a site other than the active site present on the enzyme to which a molecule (known as modulator) can bind and either enhances or inhibit the activity of enzyme.

C. Product is the resultant substance formed at the end of any chemical reaction.

D. Active site is a cavity present on the enzyme to which substrate binds and is converted to end product.

E. Substrate is the raw substance or molecule that binds to active site of the enzyme and is converted into a product.

So, the correct answer is Active site.
