Flashcards

Light-dependent reactions

The first stage of photosynthesis, which occurs in the thylakoids of chloroplasts and uses light energy to create ATP and NADPH.

Light-independent reactions (Calvin Cycle)

The second stage of photosynthesis, which occurs in the stroma of chloroplasts and uses the energy stored in ATP and NADPH to convert carbon dioxide into sugar.

Photosynthesis

The process by which plants use light energy to convert carbon dioxide and water into glucose (sugar) and oxygen.

NADPH

Energy carrier molecule produced during the light-dependent reactions; carries energy to power the Calvin Cycle.
