Key Concepts

Photosynthesis

Photosynthesis is the process by which green plants, algae, and some bacteria convert solar energy into chemical energy stored in carbohydrates. It involves the absorption of sunlight, the use of water and carbon dioxide, and the production of oxygen and sugar.

Light Reactions

Light reactions are the first stage of photosynthesis, occurring in the thylakoid membranes of chloroplasts. Here, solar energy is absorbed to drive the splitting of water molecules (photolysis), generating oxygen and producing ATP and NADPH as energy carriers.

Calvin Cycle

The Calvin cycle, also known as the light-independent reactions, takes place in the chloroplast stroma. It utilizes the ATP and NADPH produced in the light reactions to fix carbon dioxide into sugars through a series of enzymatic steps, forming the basis for organic material synthesis.

Energy Carriers (ATP and NADPH)

ATP and NADPH are crucial energy carriers generated in the light reactions. They provide the necessary energy and reducing power for the Calvin cycle to drive the fixation and conversion of carbon dioxide into sugar.

Carbon Fixation

Carbon fixation is the process by which carbon dioxide is incorporated into organic molecules during the Calvin cycle. This step is essential for building carbohydrates and sustaining the energy needs of the plant.
