Definitions:

Photosystem I

A complex of proteins and pigments in chloroplasts that absorbs light during photosynthesis, playing a key role in the light-dependent reactions by passing electrons to a series of electron carriers.

Photosystem II

A component of the chloroplasts in plants and algae involved in the light-dependent reactions of photosynthesis, particularly in water-splitting and oxygen production.

Cyclic Electron Pathway

Alternate form of the light-dependent reactions in photosynthesis that does not produce NADPH.

Noncyclic Electron Pathway

Light-dependent photosynthetic pathway that is used to generate ATP and NADPH. Because the pathway is noncyclic, the electrons must be replaced by the splitting of water (photolysis).
