  1. Question 1

    Q1. A researcher is investigating the role of phenol in the treatment of skin infections. Which of the following is a potential mechanism by which phenol exerts its antibacterial effect?

    • A) Disruption of the bacterial cell membrane leading to cell lysis
    • B) Inhibition of protein synthesis through binding to ribosomes
    • C) Denaturation of bacterial enzymes leading to loss of function
    • D) Interference with DNA replication and transcription

    Answer: Disruption of the bacterial cell membrane leading to cell lysis

    Explanation: Phenol exerts its antibacterial effect by disrupting the bacterial cell membrane, leading to cell lysis. The other options describe different mechanisms of action that are not related to phenol.
