Test Overview. An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain. Special sensors (electrodes) are attached to your head and hooked by wires to a computer. The computer records your brain's electrical activity on the screen or on paper as wavy lines.
Krebs cycle. n. 1. (Biochemistry) a stage of tissue respiration: a series of biochemical reactions occurring in mitochondria in the presence of oxygen by which acetate, derived from the breakdown of foodstuffs, is converted to carbon dioxide and water, with the release of energy.
How many ATP are produced in the Krebs cycle? The Krebs cycle happens in the mitochondria of a cell, and itâs an important part in generating energy, or ATP molecules. The Krebs cycle occurs right after glycolysis. The substance that begins the Krebs cycle is a 3-carbon molecule called pyruvic acid. The process breaks down the pyruvic acid into acetyl coenzyme A, releasing one of the carbon atoms into carbon dioxide. The cycle then combines Actyl-CoA with oxaloacetic acid to form citric acid, which has six carbon atoms.
