Question 1
Most drugs that inhibit the synthesis of the cell wall act by
◦ preventing the formation of alanine-alanine bridges.
◦ disrupting the formation of the mycolic acid layer of the cell wall.
◦ preventing the cross-linkage of NAM subunits.
◦ blocking the secretion of cell wall molecules from the cytoplasm.
◦ preventing the formation of β-lactamases.
Question 2
Most broad-spectrum antibiotics act by
◦ inhibiting metabolic pathways.
◦ inhibiting the synthesis of the cell wall.
◦ disrupting the cytoplasmic membrane.
◦ inhibiting protein synthesis.
◦ inhibiting nucleic acid synthesis.
