Which of the following chemical antimicrobial agents is matched correctly with its mechanism?
A) phenols disrupt cell membranes
B) alkyating agents block cell wall synthesis
C) acids lower surface tension
D) surfactants raise pH and denature proteins

Question

Quizplus · Accepted Answer

Phenols disrupt cell membranes by disrupting the lipid bilayer and causing leakage of intracellular components. Alkylating agents like ethylene oxide and formaldehyde can damage microbial DNA and proteins, but they do not block cell wall synthesis. Acids like acetic acid can lower the pH of the environment and inhibit microbial growth, but they do not lower surface tension. Surfactants like detergents can raise pH and denature proteins, but they do not lower it.
