Question

1. what is the name of the network of sugar molecules cross linked by polypeptides that encloses the entire bacteria?

peptidoglycan
glycosoglycan
gycosaminoglycan
lipopolyglycan

Explanation:

To answer this, we recall the structure of bacterial cell walls. Peptidoglycan is a polymer consisting of sugar molecules (glycan chains) cross - linked by short polypeptides, and it forms the mesh - like layer that encloses the entire bacterium. Glycosoglycan is not the correct term for this bacterial structure. Glycosaminoglycans are long unbranched polysaccharides in animal tissues, not bacterial cell wall components. Lipopolyglycan is also not the correct term for the bacterial cell wall network of sugar and polypeptide cross - links.

Answer:

A. peptidoglycan
