List the main anaerobic degradative pathways and the types of organisms that use them. In the first of the three stages of aerobic respiration, glucose is partially degraded to pyruvate. By the end of the second stage of aerobic respiration, which includes the Krebs cycle, glucose has been completely degraded to carbon dioxide and water. The third stage of aerobic respiration is called electron transport phosphorylation it yields many ATP molecules. Explain, in general terms, the role of oxygen in aerobic respiration.
Glycolysis occurs in the cytoplasm of the cell.
Four ATP molecules are produced by substrate-level phosphorylation for every two used during glycolysis. What will happen to the NADH produced during acetyl-CoA formation and the Krebs cycle. Calculate the number of ATP molecules produced during the Krebs cycle for each glucose molecule that enters glycolysis. Explain how chemiosmotic theory operates in the mitochondrion to account for the production of ATP molecules. Briefly describe the process of electron transport phosphorylation by stating what reactants are needed and what the products are.
