Electron Transfer Phosphorylation

Process in which electron flow through electron transfer chains sets up a hydrogen ion gradient that drives ATP formation.

NADH

Nicotinamide adenine dinucleotide (NADH) is a coenzyme found in all living cells that is involved in redox reactions, carrying electrons from one reaction to another.

Oxygen

A chemical element (O) that is critical for life, forming about 21% of the Earth's atmosphere and required for cellular respiration in most organisms.

Substrate-Level Phosphorylation

A metabolic process where a phosphate group is directly transferred from a substrate to ADP, forming ATP, without the need for an electron transport chain.
