What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs sunlight, which is essential for the light reactions.

Front

What are the light reactions?

Back

The first stage of photosynthesis where sunlight is converted into chemical energy in the form of ATP and NADPH.

Front

What is the Calvin cycle?

Back

The second stage of photosynthesis where ATP and NADPH are used to convert carbon dioxide into glucose.
