Definitions:

Electrochemical Gradient

The combined difference in concentration and charge of ions across a membrane, driving the movement of ions through channels, critical for processes like muscle contraction and nerve transmission.

ATP

Adenosine triphosphate, a molecule that carries energy within cells for metabolism.

Chemiosmosis

The movement of ions across a selectively permeable membrane, down their electrochemical gradient, which is used in cellular respiration and photosynthesis to generate ATP.

Oxidative Phosphorylation

A metabolic process that produces ATP by transferring electrons from NADH and FADH2 to oxygen via a series of electron carriers.
