Antibiotics can inhibit bacterial growth through a variety of mechanisms. Which of the following mechanisms best target and inhibit ribosome function during protein synthesis? Inhibit nucleic acid synthesis. Injure the plasma membrane. Disrupt the function of mitochondria. Disrupt lipopolysaccharide (LPS) in the outer membrane.

The beta-lactam antibiotics interfere with the formation of the glycan chains found in peptidoglycan are narrow spectrum antibiotics Interfere with enzymes known as penicillin binding proteins which are responsible for forming the tetra-peptide cross bridges in peptidoglycan are typically bacteriostatic, only inhibit growth of the bacteria when the drug is present
