Definitions:

Photosynthesis

A process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.

Photosynthesis

The process by which green plants, algae, and certain bacteria transform light energy into chemical energy, producing oxygen and glucose from carbon dioxide and water.

Light-Dependent Reactions

The phase of photosynthesis where sunlight is absorbed by chlorophyll, resulting in the production of ATP and NADPH, which are then used in the Calvin cycle.

NADP+

Nicotinamide adenine dinucleotide phosphate, a coenzyme involved in redox reactions in cells, especially in photosynthesis.
