A form of cell respiration that does not use oxygen (as opposed to aerobic cell respiration). Anaerobic respiration is less efficient than the aerobic variety and produces just 2 ATP per molecule of glucose. Anaerobic respiration has two stages: glycolysis and fermentation.
Form of cellular respiration in which some decomposers get the energy they need through the breakdown of glucose (or other nutrients) in the absence of oxygen. Compare aerobic respiration.
The incomplete intracellular breakdown of sugar or other organic compounds in the absence of oxygen that releases some energy and produces organic acids and/or alcohol.
Living or acting in the absence of oxygen. Cellular respiration in the absence of oxygen. Alzheimer's Disease A degenerative disease of the brain, characterized by clumps of neurofibrils and microscopic lesions in the brain and by confusion, disorientation, memory failure, and speech disturbances, and resulting in progressive loss of mental capacity.
Process whereby microorganisms use a chemical other than oxygen as an electron acceptor. Common "substitutes" for oxygen are nitrate, sulfate, and iron.
an-air-RO-bic res-per-A-shun Cellular respiration in the absence of oxygen. 140
A form of respiration in the absence of oxygen, in which the terminal electron acceptors may be nitrate or sulfate ions or other substances. This process yields less energy than aerobic respiration.
Smaller amounts of ATP are released when glucose is broken down in the absence of oxygen. Most organisms do fermentation as their primary method of ATP generation when oxygen is not present.
Anaerobic respiration refers to the oxidation of molecules in the absence of oxygen to produce energy. These processes require another electron acceptor to replace oxygen. Anaerobic respiration is often used interchangeably with fermentation, especially when the glycolytic pathway is used for energy production in the cell.
