BI110 Study Guide - Final Guide: Pyruvate Dehydrogenase, Electron Transport Chain, Acetyl-Coa
Document Summary
The overall process by which cells obtain energy from nutrients is called cellular respiration. In cellular respiration, atp is generated through two major mechanisms: Cellular respiration can be divided into 4 major phases: glycolysis, a. pyruvate decarboxylation. Pyruvate transported from cytosol to the mitochondrial matrix. Carboxyl group of pyruvate is removed to form co2. Coa to form acetyl coa: citric acid cycle. Acetyl coa citrate: oxidative phosphorylation. Organic molecules are chemically interchangeable: gluconeogenesis: amino acids and glycerol can be converted to glucose, some fatty acids and amino acids can be converted to pyruvate and others. Module 25 cellular respiration i - digestion & glycolysis. Catabolic pathways in which carbohydrates (glucose) are metabolized. 10 enzyme catalyzed reactions are coupled together in the cytosol in order to do so. Glucose (6 carbons) are oxidized into 2 molecules of pyruvate (3 carbons each) Glycolysis initially requires the hydrolysis of 2 atp molecules: in turn 4 atp molecules and 2 nadh molecules are formed.
