  1. Question 1

    Q1. Comparing ATP synthesis, the process of chemiosmosis in chloroplasts is driven by:

    • A) Chemical energy from food
    • B) Light energy
    • C) Thermal energy
    • D) Electrical energy

    Answer: Light energy

    Explanation: Chloroplasts use light to create a proton gradient. Mitochondria are tempting because they use energy from chemical bonds for chemiosmosis.
