Question

Explain mode of action Antibiotic penicillin and streptomycin? [2 marks]​

Answer 1

Answer:

Penicillin acts by inhibiting the transpeptidase enzyme - it mimics a peptidoglycan chain and an ester is formed that joins the penicillin to the enzyme.

Streptomycin belongs to a class of drugs known as aminoglycoside antibiotics. It works by killing the organisms that cause the infection. This drug may also be used to treat other serious infections (e.g., Mycobacterium avium complex-MAC, tularemia, endocarditis, plague) along with other medications.
