Cellular Respiration vs. Fermentation: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 16, 2023
Cellular respiration is a process where cells convert nutrients into energy using oxygen. Fermentation is an anaerobic process that converts sugar to acids, gases, or alcohol.

Key Differences

Cellular respiration is a complex process where cells convert glucose and oxygen into energy, water, and carbon dioxide. In contrast, fermentation is a simpler, anaerobic process that breaks down glucose without oxygen, producing less energy.

Cellular respiration occurs in the mitochondria of cells and involves several steps, including glycolysis, the Krebs cycle, and electron transport chain. Fermentation, however, takes place in the cytoplasm and typically includes just glycolysis, leading to the production of lactic acid or alcohol.

Cellular respiration is more efficient than fermentation, generating up to 38 ATP molecules per glucose molecule, whereas fermentation produces only about 2 ATPs.

Oxygen is essential for cellular respiration; it serves as the final electron acceptor in the electron transport chain. Fermentation occurs in the absence of oxygen, making it crucial for organisms in oxygen-depleted environments.

Cellular respiration results in the complete oxidation of glucose, leading to carbon dioxide and water as waste products. In fermentation, incomplete oxidation of glucose produces ethanol or lactic acid as by-products.
