Question

Part of enzyme where substrate is changed into product is called -----------

• A. Allosteric site
• B. Active site
• C. Cofactor
• D. Prosthetic group

Answer 1

The correct option is B Active site

Part of an enzyme where substrate molecules get attached is known as an active site. On attachment to the active site, the substrate is changed into the product. The active site has a residue which helps in the attachment of substrate. The substrate molecules form a temporary bond with the enzyme at the active site. Bonds like hydrogen bonds, hydrophobic interactions, or temporary non-covalent interactions are formed which leads to the formation of the enzyme-substrate complex.

So, the correct answer is option B.
