Glycerol backbone of a fat molecule can be converted to glyceraldehyde-3-phosphate, an intermediate in glycolysis. Assuming that the single glyceraldehyde-3-phosphate undergoes complete oxidation to CO₂, how many ATPs are produced by oxidative phosphorylation only (i.e. exclude ATPs from substrate level phosphorylation) from a single fat molecule? O 20 O 18 O 17 O 15 08

Consider ten glucose molecules that enter a cell. How many ATP can be generated by the complete catabolism of these into CO2 and H2O? If all ten are first incorporated into glycogen, liberated from glycogen, and then fully catabolized into CO2 and H2O, does the ATP tally increase, decrease or stay the same? Consider that 1 UTP = 1 ATP. Explain. Describe the processes which produce ATP and provide a balanced equation of glucose, CO2, H2O and O2
Assuming that the glycerol 3-phosphate shuttle is operative, a complete oxidation of three molecules of glucose (by a eukaryotic cell) into carbon dioxide and water would produce approximately ATP molecules via oxidative phosphorylation only. (Consider NADH = 2.5 ATP and FADH2 = 1.5 ATP)
Lactate dehydrogenase (LDH) plays an essential role in an exercising muscle, especially when the level of excursion surpasses the ability of circulatory systems ability to supply adequate oxygen. What is the main reason LDH is so important to the muscle under these conditions? It produces one mole of ATP via substrate level phosphorylation. It resupplies NAD+ to glyceraldehyde 3-phosphate dehydrogenase. It decreases pH thus decreasing the dissociation rate of oxygen from hemoglobin It produces NADH for energy while converting pyruvate into lactate. It removes excess lactic acid from the muscle to create pyruvate. Next
