  1. Question 1

    Q1. A cell membrane is being studied for its fluid-mosaic properties. Which characteristic of phospholipids allows them to form a bilayer unlike neutral fats?

    • A) Amphipathic nature
    • B) Complete hydrophobicity
    • C) Presence of three fatty acids
    • D) Lack of phosphate groups

    Answer: Amphipathic nature

    Explanation: Phospholipids are amphipathic, containing both hydrophilic and hydrophobic regions. Neutral fats are tempting but they are entirely hydrophobic and non-polar.
