Cell Biology
Adenosine triphosphate (ATP) is the energy rich compound found in all living cells. Each ATP molecule is made up of adenosine, an organic molecule. A single adenosine molecule has three inorganic phosphates attached to it. ATP is synthesized in mitochondria of cells from respiratory substrates (mainly glucose) in a process known as respiration. This process occurs in three stages- glycolysis, citric acid cycle, and electron transport. The first stage, glycolysis, takes place in cytoplasm of a cell. In this stage glucose is split forming two molecules of 3-carbon molecule called pyruvic acid. This process does not need oxygen to Continue reading...
