Inhibition of cell wall synthesis.

Inhibition of nucleic acid synthesis.

Inhibition of protein synthesis.

Inhibition of synthesis of essential metabolites.

Injury to the plasma membrane. Here are the Questions: Which of the following best describes the mode of action of Penicillin? Which of the following best describes the mode of action of Sulfamethoxazole (a sulfa drug)? Which of the following best describes the mode of action of Tetracycline?

Answer 1

1. Pencillin inhibits the synthesis of the peptidoglycan layer of bacterial cell walls.

2. Tetracyclin inhibits the elongation of protein synthesis by block the A site on the ribosome, preventing the binding of aminoacyl tRNAs.

3. Sulfamethoxazole inhibits the synthesis of essential metabolites.
