  1. Question 1

    Q1. A student examines a phospholipid molecule diagram in the textbook. Which component acts as the bridge between the hydrophilic head and the hydrophobic tails?

    • A) Choline group
    • B) Phosphate group
    • C) Glycerol molecule
    • D) Sphingosine

    Answer: Glycerol molecule
