Hill Reaction

The light-dependent stage of photosynthesis, occurring within the thylakoid membrane of chloroplasts, characterized by the absorption of light energy by chlorophyll, photolysis of water, and release of oxygen.

Calvin Cycle

The light-independent stage of photosynthesis, occurring in the stroma of chloroplasts, where carbon dioxide is reduced to carbohydrates using ATP and NADPH produced during the Hill Reaction.

Photolysis

The splitting of water molecules using light energy in the Hill Reaction, releasing oxygen and electrons into the electron transport chain.
