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 are known to disrupt cell membranes by causing protein denaturation and lipid solubilization. Alkylating agents interfere with DNA replication and RNA synthesis by covalently binding to DNA and preventing its uncoiling. Acids reduce the growth of microbes by lowering the pH of the surrounding medium, making it unsuitable for their survival. Surfactants lower the surface tension of liquids, which enhances their wetting properties, and can also denature proteins by disrupting their three-dimensional structure.
