Fermentation & Anaerobic Respiration definitions Flashcards

A process that allows glycolysis to continue by regenerating NAD+ in the absence of oxygen.

Respiration using alternative electron acceptors like nitrate or sulfate, producing more ATP than fermentation.

The first step of cellular respiration that occurs in the cytoplasm, producing a small amount of ATP.

An electron carrier that is regenerated during fermentation to allow glycolysis to continue.

An electron carrier that accumulates when oxygen is absent, leading to fermentation.

A product of lactic acid fermentation, formed when pyruvate is reduced by NADH.

A type of alcohol produced during alcohol fermentation when pyruvate is reduced.

A series of complexes that transfer electrons, backed up without oxygen as the final acceptor.

A key intermediate in metabolism, reduced to lactic acid or ethanol during fermentation.

The energy currency of the cell, produced in small amounts during glycolysis and fermentation.

A process where pyruvate is reduced to lactic acid, regenerating NAD+ for glycolysis.

A process where pyruvate is reduced to ethanol, regenerating NAD+ for glycolysis.

An alternative electron acceptor used in anaerobic respiration instead of oxygen.

An alternative electron acceptor used in anaerobic respiration, allowing ATP production.

A process that requires oxygen as the final electron acceptor, producing the most ATP.
