Definitions:

Cyclic Electron Transport

A process in photosynthesis where electrons are recycled around the photosystem I, contributing to the production of ATP without the production of NADPH.

Noncyclic Electron Transport

A pathway of photosynthesis where electrons are transported from water to NADP+, producing oxygen and contributing to the generation of ATP.

NADPH

A coenzyme involved in anabolic reactions and antioxidative processes, crucial for cellular energy metabolism.

Photosystem II

A component of the photosynthesis process in plants and algae that captures photons to initiate the splitting of water, releasing oxygen.
