Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

What is the significance of ATP in photosynthesis?

Back

ATP (adenosine triphosphate) provides the energy needed for the light-independent reactions (Calvin cycle) to synthesize glucose.

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons, and it is split during the light-dependent reactions to release oxygen.

Front

What is the function of the Calvin cycle?

Back

The Calvin cycle is the light-independent reaction that uses ATP and NADPH to convert carbon dioxide into glucose.
