Question 3 • Biology

Which events take place in the light-dependent reactions of photosynthesis?

Answer
A
Light energy is captured by plants; light energy is converted to chemical energy.
B
Light energy is converted to chemical energy; chemical energy is used to make sugar.
C
Light energy is captured by plants; light energy is used to make sugar.
D
Light energy is converted to sugars; sugars are broken down for energy.

Explanation

In the light-dependent reactions, chlorophyll captures light energy, and that energy is converted into chemical energy stored in ATP and NADPH. Sugar is made later in the light-independent reactions, so choices that say the light-dependent reactions make sugar are incorrect. The correct choice is D: light energy is captured by plants and converted to chemical energy.
