Question

The most important structural component of bacterial cell walls is _____.
A)teichoic acid
B)lipotechoic acid
C)peptidoglycan
D)glutamic acid

Accepted Answer

Peptidoglycan is the most important structural component of bacterial cell walls. It provides rigidity and protects the cell from osmotic lysis. Teichoic and lipoteichoic acids are found in some bacteria and are attached to peptidoglycan. Glutamic acid is an amino acid that may be found in bacterial cell walls, but it is not a major structural component.
