Q: Which bacterial enzyme is inhibited by Fluoro quinolone derivative?
  • A. DNA gyrase
  • B. Folate synthase
  • C. Topoisomerase II
  • D. β lactamase
Correct Answer: Option A - Bacterial enzyme DNA gyrase is inhibited by Fluoro quinolone derivative. Fluoro quinolene stops bacterial growth by its inhibitory action upon enzymes essential for bacterial DNA replication.
A. Bacterial enzyme DNA gyrase is inhibited by Fluoro quinolone derivative. Fluoro quinolene stops bacterial growth by its inhibitory action upon enzymes essential for bacterial DNA replication.

Explanations:
