All mechanisms of glucose metabolism begin with glycolysis and produce 2 pyruvates, 2 ATP and 2 NADH. Make a table comparing aerobic and anaerobic metabolism (after glycolysis) to describe how pyruvate is metabolized. Columns: Cell Respiration, Lactic Acid, Alcohol Fermentation Rows: Where (in the cell) does pyruvate go? What happens to pyruvate (explain in step by step detail)? Is pyruvate oxidized or reduced? What energy-storing molecules are made? What energy-storing molecules are used? What byproducts str produced (CO2 or H2O)?...
