Definitions:

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.

Glycolysis

Glycolysis is a metabolic pathway that breaks down glucose into pyruvate, generating small amounts of energy in the form of ATP.

Lactate Accumulation

The build-up of lactate in muscles during strenuous exercise when oxygen levels are low, often leading to fatigue.
