Which of the Following May Be a Component of Bacterial

Question

Which of the following may be a component of bacterial cell walls?
A) carrageenan
B) lipoteichoic acids
C) mycolic acid
D) tubulin
E) both lipoteichoic and mycolic acids

Accepted Answer

Lipoteichoic acids are components of the cell wall in Gram-positive bacteria, providing structural support and playing roles in cell division. Mycolic acid is a waxy substance found in the cell walls of Mycobacterium species, such as those causing tuberculosis and leprosy, contributing to their virulence and resistance to certain chemicals and dyes. Carrageenan is a polysaccharide found in red algae and is not a component of bacterial cell walls. Tubulin is a protein involved in cell structure and movement in eukaryotic cells, not in bacteria.
