Document Summary

Primary goal is to transform the potential energy found in food molecules into a form that can be used for metabolic processes, atp. Enzymes break down a molecule of glucose into two molecules of pyruvate. Acetyl coenzyme a (formed from oxidation of pyruvate) enters a metabolic cycle where it is completely oxidized to carbon dioxide. Nadh synthesized by both glycolysis and citric acid cycle is oxidized, with the literated electrons being passed along etc until they are transferred to oxygen, producing water. Free release during electron transport id used to generate a proton gradient across a membrane, which, is used to synthesize atp. Mitochondria is the site of cellular respiration in eukaryotes. Glycolysis and citric cycle (krebs cycle) occurs in cytosol in archaea and bacteria cells. First metabolic pathways, how pathway is regulated to meet the energy needs of cell. Is universal, being found in all three domains of life (archaea, bacteria, eukaryotic)

In glucose metabolism, glucose enters into the Glycolysis pathway. The products of glycolysis are then utilized by the Pyruvate Dehydrogenase Complex, which shuttles its products into the Citric Acid Cycle. The combined activities of these pathways directly synthesize a number of molecules of ATP, GTP, NADH and FADH₂. Indicate the net gain of each of the molecules listed in the table below if a single glucose molecule were to be completely and sequentially metabolized by all three processes.
