Question 3 • First Semester Biology

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

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

Explanation

In the light-dependent reactions, chlorophyll captures light energy and the reactions convert it into chemical energy stored in molecules such as ATP and NADPH. Making sugar happens later, in the light-independent reactions, so choice C includes an event from the wrong stage. The correct choice is “Light energy is captured by plants; light energy is converted to chemical energy.”
