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.
During each Krebs cycle, eight reactions should occur. As the reactions happen, the energy currency of the cell, adenosine triphosphate, known as ATP, is made. Continue Reading. Electrons are also given off during the Krebs cycle, which fuel the process of oxidative phosphorylation. Oxidative phosphorylation is a major source of ATP and energy. The first reaction in the cycle is the addition of an acetyl group to oxaloacetate by citrate synthase.
