The bactericidal antibiotic penicillin kills bacterial cells by preventing peptidoglycan (cell wall) biosynthesis. Which of the following phases of the bacterial growth curve would you expect penicillin to be most active against?
Homework Answers
Ans:- logarithmic phase.
Penicillin is the first antibiotic discovered, is one of the several antibacterials within a class beta lactams. This beta- lactam antibacterials block the cross-linking of peptide chains during biosynthesis of new peptidoglycan in the bacterial cell wall. So the bacteria lengthen,but can't divide. Due to this weak cell wall ruptures.

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....
