Question

3.4.2 test (cst): computer-scored unit test
a (solar energy arrow), b, c, d, e, f, g. light dependent reactions, calvin cycle.
options:
a. solar energy is converted and stored in chemical bonds.
b. energy in food is released and stored in atp molecules.
c. chemical energy is converted to kinetic energy.
labels: outer membrane, intermembrane space, inner membrane, granum (stack of thylakoids), thylakoid, stroma (fluid)

Explanation:

The diagram shows a chloroplast with light - dependent reactions and the Calvin cycle. Option A: Light - dependent reactions (where A, solar energy, is involved) convert solar energy into chemical energy (like in ATP and NADPH, which are used in the Calvin cycle to store energy in chemical bonds of glucose). Option B: Releasing energy from food and storing in ATP is cellular respiration, not what's shown here (chloroplast is for photosynthesis). Option C: Chemical to kinetic energy isn't related to photosynthesis in chloroplasts. So A is correct.

Answer:

A. Solar energy is converted and stored in chemical bonds.
