Solution
Phenolics, which are often used as disinfectants or antiseptics, can kill microbes through several mechanisms:
-
Disrupting the cell membrane: Phenolics can interact with the lipid bilayer of the cell membrane, causing it to lose its integrity and function. This can lead to leakage of cellular contents and eventually cell death.
-
Denaturing metabolic enzymes: Phenolics can also denature proteins, including metabolic enzymes, which are crucial for the survival and growth of the microbe. When these enzymes lose their structure, they can no longer function properly, which can inhibit the microbe's metabolism and lead to its death.
The other options mentioned - inhibiting RNA synthesis, disrupting the cell wall, causing mutations in DNA, and inhibiting protein synthesis - are not typically associated with the antimicrobial action of phenolics.
Similar Questions
To be acceptable, an antimicrobial agent must inhibit or destroy the pathogen without damaging the host (i.e., the infected person). To accomplish this, the agent must target a metabolic process or structure possessed by the pathogen but not possessed by the host. The five most common mechanisms of action of antimicrobial agents are as follows, except: (1 Point)• Inhibition of cell wall synthesis• Damage to cell membranes• Inhibition of nucleic acid synthesis (either DNA or RNA synthesis)• Inhibition of protein synthesis• Inhibition of toxins
The phenolic was widely used in many products as a disinfectant and antiseptic, but was banned in consumer products in 2017 due to concerns about development of resistance in microbes.
