Inhibitors to cell membrane synthesis are
A. Polymixin
B. Gramicidin and Circulin
C. Tyrocidin
D. All of the above
Answer: Option D
Solution(By Examveda Team)
Inhibitors to cell membrane synthesis are Polymixin, Gramicidin, and Circulin, also Tyrocidin.Polymyxin antibiotics inhibit bacterial membranes after binding to lipopolysaccharides (LPSs), interacting with lipid A of the outer membrane, and acting as a detergent by disrupting the membrane phospholipids, causing cellular permeability and demise.
Gramicidin and circulin are antibiotic peptides that can be incorporated into the monolayers of cell membranes.
Tyrocidine is a mixture of cyclic decapeptides produced by the bacteria Bacillus brevis found in soil.
