Light Dependent

Light-Dependent Reaction

First part of photosynthesis that converts light energy into chemical energy, essential for producing ATP and NADPH.

ATP (Adenosine Triphosphate)

Energy storage molecule generated during the light-dependent reaction, crucial for the next stage of photosynthesis.

NADPH (Nicotinamide Adenine Dinucleotide Phosphate)

Reduced electron carrier produced in the light-dependent reaction, important for the Calvin Cycle.

Light Absorption

Process where chlorophyll absorbs sunlight, converting light energy into chemical energy.

Photolysis

Splitting of water molecules into electrons, hydrogen ions, and oxygen through light absorption.

PSII (P680)

Photosystem II where chlorophyll absorbs light energy, initiating electron transport.

Electron Transport Chain (ETC)

Series of membrane proteins where electrons move, releasing energy and pumping hydrogen ions across the thylakoid membrane.

ATP Formation

Process involving chemiosmosis to produce ATP using energy from the ETC and hydrogen ions.

PSI (P700)

Photosystem I where electrons are re-energized by light absorption, leading to NADPH formation.

NADPH Formation

Process where electrons are absorbed by NADP+ and hydrogen, resulting in the production of NADPH.
