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)? What other molecules are needed? What other molecules are produced?

Which of the following characteristics applies to fermentation? Select all answers that apply. It is aerobic. It is anaerobic. It takes place in mitochondria. It takes place in the cytoplasm. It produces alcohol, lactic acid, or other molecules as byproducts (depending on the species). It produces a net gain of 32 to 38 molecules of ATP per glucose molecule. It produces a net gain of 2 molecules of ATP per glucose molecule. It regenerates ADP to keep glycolysis running. It...

Which will produce more ATP: i). Three molecules of glucose that are metabolized by glycolysis to yield pyruvate orii). Three molecules of glucose that enter the Pentose Phosphate pathway and are converted to two molecules of fructose-6-phosphate and one molecule of glyceraldehyde-3-phosphate, which can then enter glycolysis. Explain your metabolic calculations/logic. NOTE: Do not consider ATP equivalents from NADH or NADPH in your answer.
