In a liver cell, if a single molecule of glucose undergoes glycolysis
In a liver cell, if a single molecule of glucose undergoes glycolysis, and the citrate cycle completes along with the electron transport chain, how many net ATP molecules are produced based on the chemical potential energy contained in the glucose substrate? Assume that no other pathways were involved.

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.

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)?...

which is true? 1. catabolism of glucose is endergonic 2. glycolysis is aerobic and produced ATP by oxidative phosphorlyation 3. phosphofructokinases can exist in different permutations 4. during cellular respiration, glucose is reduced to CO2, and either O2 or organic molecule is oxidized An abundance of which increases activity of pyruvate dehydrogenase? 1. ADP 2.NADH 3. lipoic acid 4. TPP

The expression of the GLUT-1 glucose transporter usually correlates with the rate of anaerobic glycolysis. The number of cancer cells show increased synthesis of the GLUT-1 transporter due to c-Myc and HIF-1 alpha. Why would cancer cells need to increase the synthesis of the glucose transporter? Given what you know about the rates of ATP production by glycolysis and the citric acid cycle, propose two reasons why many cancer cells preferentially use glycolysis for ATP production. In addition to energy...

6. Name the stages of cellular respiration and state the region of the eukaryotic cell where each stage occurs. Summarize the events of glycolysis. Identify the nutrient being oxidized, the products of glycolysis, and the energy transfer reactions. What is the net amount of ATP made per glucose? Where is the remainder of the energy? Describe where pyruvate is oxidized to acetyl CoA, what molecules are produced, and how 7. 8. this process links glycolysis to the citric acid cycle.

2. Concept Map: construct a concept map that depicts the metabolism of glucose through glycolysis, the TCA cycle, electron transport and oxidative phosphorylation. For your drawing, include where in the cell these processes occur. The map should show the names of all intermediates (but do not show structures), the names of all enzymes, all products and cofactors required/produced and all membrane complexes. (10) Hint: Include Glucose →glycolysis steps → pyruvate → acetylCoA → TCA cycle steps → electron transport chain...
