Document Summary

A cumulative function of three metabolic stages: glycolysis, the krebs cycle, the electron transport chain and oxidative phosphorylation. Glycolysis is a catabolic pathway that: occurs in the cytosol, partially oxidizes glucose (6c) in two private (3c) molecules. The krebs cycle is a catabolic pathway that: occurs in the mitochondrial matrix, completes glucose oxidation by breaking down pyruvate derivative (acetyl coa) into carbon dioxide. Glycolysis and the krebs cycle produce: a small amount of atp by substrate-level phosphorylation, nadh by transferring electrons from substrate to nad+ (krebs cycle also produces. Is located at the inner membrane of the mitochondrion: accepts energized electrons from reduced coenzymes (nadh and fadh2) that are harvested during glycolysis and krebs cycle, couples this exergonic slide of electrons to atp synthesis or oxidative phosphorylation. This process produces most (90%) of the atp. During glycols is each glucose molecules is broken down into two molecule of the compound private.
