In cellular respiration, the electron transport stage is when most adenosine triphosphate (ATP) is produced. Electron transport is the third stage in cellular respiration.
Cellular respiration involves a series of complex reactions. The first phase of cellular respiration is glycolysis, which involves splitting glucose. This phase is carried out in several steps. The end result is the production of pyruvic acid. After pyruvic acid is produced, the Krebs cycle begins. The Krebs cycle, which is the second phase of cellular respiration, is sometimes referred to as the citric acid cycle. The Krebs cycle first produces citric acid, and it produces carbon dioxide as an end product. Electron transport is the last stage of aerobic respiration in cellular respiration. It results in the production of adenosine triphosphate, or ATP. ATP is a molecule that supports a variety of life functions. It is found in the nucleoplasm and cytoplasm of all cells, and helps organisms perform physiological functions. During anaerobic respiration, ATP is synthesized through glycolysis. In aerobic production, ATP is produced by mitochondria in addition to glycolysis.
