Chloroplast

Organelles found in plant and algae cells that conduct photosynthesis, converting light energy, water, and carbon dioxide into sugars and oxygen.

Chemiosmosis

The movement of ions across a semipermeable barrier, generating ATP in the process of cellular respiration or photosynthesis.

ATP Synthesis

ATP Synthesis is the biochemical process by which cells produce ATP (Adenosine Triphosphate), utilizing energy from food molecules or sunlight in photosynthetic organisms to power cellular functions.

Light-Dependent Reactions

Reactions of photosynthesis in which light energy absorbed by chlorophyll is used to synthesize ATP and usually NADPH. Include cyclic electron transport and noncyclic electron transport.
