Cellular Respiration Notes
Cellular Respiration Wednesday, March 06, 2013 5:23 PM ? Cellular Respiration Cellular respiration - an ATP-generating process that occurs within cells; energy is extracted from energy-rich glucose to form ATP from ADP and phosphate C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy Glucose + air = carbon dioxide + water + energy Aerobic respiration - cellular respiration in the presence of O2; divided into three components: glycolysis, the Krebs cycle, and oxidative phosphorylation ? Glycolysis Glycolysis - the decomposition (lysis) of glucose (glyco) to pyruvate (or pyruvic acid); nine intermediate products are formed and, of course, each one is catalyzed by an enzyme; in six of the steps, magnesium ions are cofactors that promote enzyme activity; summary of the steps:
