Definitions:

Electron Transport Chain

A sequence of electron carriers in the mitochondria that transfers electrons from donors to acceptors, releasing energy used to produce ATP.

NADH

Nicotinamide adenine dinucleotide (reduced form), a coenzyme involved in the electron transport chain, crucial for ATP production in cells.

FADH2

FADH2 is a reduced form of flavin adenine dinucleotide, a coenzyme involved in redox reactions within the cell.

Glycolysis

The metabolic pathway that converts glucose into pyruvate, releasing energy and forming ATP and NADH, occurring in the cytoplasm of cells.
