Which of the Following Interferes with Cell Wall Synthesis by Blocking

Question

Which of the following interferes with cell wall synthesis by blocking alanine bridge formation?
A) beta-lactams
B) cycloserine
C) bacitracin
D) vancomycin
E) both cycloserine and vancomycin

Accepted Answer

Cycloserine and vancomycin both interfere with cell wall synthesis by blocking alanine bridge formation. Cycloserine inhibits the incorporation of alanine into the cell wall, while vancomycin binds to the alanine-alanine bridges, preventing their formation.
