Question

multiple choice question
a compound in which polysaccharides are linked to peptide fragments that provides the main source of structural support to the bacterial cell wall is

peptidoglycan
lipopolysaccharide
phospholipid
chitin
cellulose

Explanation:

Peptidoglycan is a compound where polysaccharides are linked to peptide fragments and it is the main structural - support component of the bacterial cell wall. Lipopolysaccharides are mainly found in the outer membrane of Gram - negative bacteria and are not the main structural support. Phospholipids are components of cell membranes, not the main structural support of the cell wall. Chitin is found in the cell walls of fungi and exoskeletons of arthropods. Cellulose is a major component of plant cell walls.

Answer:

peptidoglycan
