The light-dependent reactions of photosynthesis are also known as the light cycle.

The light-dependent reactions of photosynthesis are also known as the light cycle or the Calvin cycle.

To find out which one is the correct answer, we can break down each option:

1. The CO2 cycle: Photosynthesis involves the uptake of carbon dioxide (CO2) from the atmosphere, but it is not specifically referred to as a cycle itself. The CO2 is used in the light-independent reactions (Calvin cycle) to produce glucose.

2. The light cycle: This is an accurate term to describe the light-dependent reactions of photosynthesis. These reactions occur in the thylakoid membrane of the chloroplasts and are responsible for capturing light energy and converting it into chemical energy in the form of ATP and NADPH. These energy-rich molecules are then used in the next stage of photosynthesis.

3. The glucose cycle: While glucose is an essential product of photosynthesis, it does not describe the light-dependent reactions. Glucose is formed in the light-independent reactions (Calvin cycle) where carbon dioxide, ATP, and NADPH are used to synthesize glucose.

4. The Calvin cycle: This term refers to the light-independent reactions of photosynthesis, which take place in the stroma of the chloroplasts. The Calvin cycle uses ATP and NADPH produced in the light-dependent reactions to fix carbon dioxide and convert it into glucose.

Therefore, the correct answer is the "Calvin cycle," also known as the light-independent reactions, while the light-dependent reactions are referred to as the "light cycle."
