Definitions:

Fermentation

Anaerobic glucose-breakdown pathway that produces ATP without the use of electron transfer chains.

Pyruvate

A critical molecule in cellular metabolism that marks the end of glycolysis and the starting point for the Krebs cycle in aerobic respiration or fermentation in anaerobic conditions.

NAD+

Nicotinamide adenine dinucleotide, a coenzyme found in all living cells that is critical in metabolic processes, particularly in redox reactions.

NADH

Nicotinamide adenine dinucleotide (NADH) serves as an electron carrier, playing a crucial role in cellular energy production during the process of oxidative phosphorylation.
