Answer #1

C. The number of NAG and NAM sheets, and the type and number of amino acids in the interbridge.

In the gram negative bacteria , the cell wall is composed of the single layer of peptidoglycan and a outer membranous layer. The cell wall of gram negative bacteria is comparatively thinner than the gram positive bacteria. The amino acids and amino sugars are present in the cell wall which determines its thickness. It also consists of two joined sugars NAG and NAM which are N acetyl glucosamine and N acetylmuramic acid in the monomer.

1. Neosporin® ointment contains neomycin, streptomycin, and bacitracin. Like penicillin, bacitracin inhibits peptidoglycan synthesis, but it does so using a different mechanism. Penicillin binds to the _____ [D-Ala-D-Ala in peptidoglycan/transpeptidase(PBP2)/bactoprenol carrier molecule] and prevents cross-linking in the peptidoglycan. Bacitracin binds to the ____ [D-Ala-D-Ala in peptidoglycan/transpeptidase(PBP2)/bactoprenol carrier molecule] and prevents transport of ______ [amino acids/nucleotide bases/NAM-NAG monomers/D-Ala-D-Ala] across the _____ [plasma/outer] membrane to the growing peptidoglycan chain. 2. Competitive inhibition describes the mechanism of action for: a. penicillin b. bacitracin...
