Question

Bacterial cell walls are composed of peptidoglycan complex polysaccharide. Peptidoglycan, in turn, is composed of two types of regularly alternating sugar molecules, called N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM), which are structurally similar to glucose?

A) Ribose
B) Sucrose
C) Fructose
D) Maltose

Answer 1

Bacterial cell walls are composed of peptidoglycan, a complex polysaccharide made up of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM). Peptidoglycan provides structural support and protection to bacteria.

Step-by-step explanation:

Bacterial cell walls are composed of peptidoglycan, which is a complex polysaccharide. Peptidoglycan is made up of two types of sugar molecules, N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM). These sugar molecules are structurally similar to glucose. Peptidoglycan provides bacteria with structural support and protection.
