Zak Murdock Pd. 1 11/2/07 Video Questions 1) Aerobic cellular respiration is the process by which ATP is produced by cells through the complete oxidation of organic compounds using oxygen. Aerobic respiration takes place in three stages, glycolysis, the citric acid cycle also known as the Kreb’s cycle, and electron transport phosphorylation. Glycolysis is the first step in cellular respiration. During glycolysis, glucose is partially oxidized and broken down into three carbon molecules known as pyruvates, or pyruvic acid. During the process of glycolysis, 4 ATP molecules are produced with a net gain of 2, as well as 2 molecules of NADH. After the process of glycolysis is finished, the pyruvate is processed in order to gain 2 more NADH molecules and lose one carbon. The remaining two carbons are then used for the complicated reactions of the Kreb’s Cycle. The Kreb's cycle converts pyruvate to CO2 and reducing energy and phosphorylated energy. The three-carbon pyruvate reacts and a carbon is lost as CO2. The remaining two-carbon compound is not liberated but it does bind to a special molecule known as coenzyme A to form acetyl CoA. During the reactions of the Kreb’s cycle, the two carbons are used to produce 8 or
