  1. Question 1

    Q1. A researcher is investigating the role of phenol in the formation of atherosclerotic plaques. Which of the following is a potential mechanism by which phenol contributes to plaque formation?

    • A) Inhibition of lipoprotein lipase leading to increased triglyceride levels
    • B) Stimulation of lipid peroxidation leading to the formation of oxidized LDL
    • C) Inhibition of cholesterol esterification leading to increased free cholesterol levels
    • D) Enhancement of HDL cholesterol levels leading to increased reverse cholesterol transport

    Answer: Stimulation of lipid peroxidation leading to the formation of oxidized LDL

    Explanation: Phenol stimulates lipid peroxidation, leading to the formation of oxidized LDL, which contributes to plaque formation. The other options describe different mechanisms of action that are not related to phenol.
