Question

Penicillin interferes with ……….synthesis of actively growing sensitive microorganisms

a. Protein

b. Nucleic acid

c. Cell wall

d. Cell membrane

Answer 1

Answer : c. cell wall

Explanation:

Penicillin G inhibits the synthesis of bacterial cell walls, causing growing cells to burst. The enzyme transpeptidase catalyzes reactions that form the cell wall. The enzyme forms a complex with penicillin G, and the carbonyl group reacts with a serine hydroxyl group contained in the active site of the enzyme.
