penicillin kills bacteria bu affecting its protein sunthesis cell wall DNA gurase all of the above
Homework Answers
- Penicillin is a Beta-lactum antibiotic.
- Penicillin is specific in targeting bacterial cell (more effective against Gram positive bacteria), as it inhibits cell wall synthesis of bacterial cell.
- When bacterial cells try to divide by binary fission, new cell wall formation is required, which is prevented by penicillin.
- Hence, bacterial cells cannot divide.

Penicillin is an enzyme-inhibiting antibiotic that kills bacteria by suppressing the synthesis of bacterial cell walls. The bacterial cell wall is made of cross-linked peptidoglycan, which is synthesized from peptidoglycan monomers by transpeptidase enzymes. How does penicillin suppress the synthesis of bacterial cell walls? O Penicillin binds to the cross-linked peptidoglycan, preventing further bacterial cell wall growth. Penicillin signals the bacterial cell to stop producing the transpeptidase enzymes. Penicillin binds to the transpeptidase enzymes, preventing the synthesis of cross-linked peptidoglycan....
