Which statement is most accurate regarding the first stage of photosynthesis?

Question

A. radiant energy is converted into chemical energy, and this is a light-dependent stage
B. Sugar molecules like glucose are formed, and this is light-dependent stage
C. Radiant energy is converted into chemical energy, and this is a light-independent stage
D. Sugar molecules like glucose are formed, and this is a light-independent stage

Answer 1

The most accurate statement regarding the first stage of photosynthesis is:

A. radiant energy is converted into chemical energy, and this is a light-dependent stage.

In the first stage of photosynthesis, also known as the light-dependent reactions, sunlight is captured by chlorophyll and used to convert water and sunlight into oxygen, ATP, and NADPH, which are forms of chemical energy. The formation of sugar molecules, such as glucose, occurs in the second stage, known as the Calvin cycle, which is light-independent.
