Definitions:

Chlorophyll A

A key photosynthetic pigment found in plants, algae, and cyanobacteria, responsible for the green color and vital for capturing light energy to produce food.

Light-Dependent Reactions

Series of biochemical processes in photosynthesis that require light to produce ATP and NADPH, occurring in the thylakoid membranes of chloroplasts.

ATP

Adenosine Triphosphate is a high-energy molecule found in every cell. Its job is to store and supply the cell with needed energy.

NADPH

Nicotinamide adenine dinucleotide phosphate, a coenzyme involved in anabolic reactions, such as lipid and nucleic acid synthesis, by providing the reducing power.
