What is the net yield of ATP produced by the anaerobic fermentation of one molecule of...
What is the net yield of ATP produced by the anaerobic fermentation of one molecule of galactose to two molecules of lactate in myocytes. The answer is 2 ATP but what is the explanation for that? I keep getting 3 ATP since galactose enters the glycolytic pathway at Glucose 6 phosphate and bypasses the hexokinase ATP retirement, thus giving the regular 2 ATP from glycolysis and an additional ATP that was not used in the hexokinase reaction. Thus giving 3...

In skeletal muscle under anaerobic conditions, pyruvate is further reduced to lactate. What is the net equation for the payoff phase of glycolysis? glyceraldehyde-3-phosphate + 2 ATP + Pi ---> lactone + NAD+ glucose+2ATP ---> 2Glyceraldehyde-3-Phosphate + 2ADP + 2H+ 2glyceraldehyde-3-phosphate + 4ADP + 2Pi >2Lactate + 4ATP None of the above

The ATP yield for a molecule depends on where it enters glycolysis or the citric acid cycle. The yield can be compared to the net yield of glucose, 30 ATP. Determine the net ATP yield of each starting molecule when fully oxidized to CO2. Assume that glycolysis, the citric acid cycle, and oxidative phosphorylation are fully active. net ATP yield from fructose 1,6-bisphosphate: ATP molecules net ATP yield from galactose: ATP molecules net ATP yield from dihydroxyacetone phosphate: ATP molecules...

2. During exercise, skeletal muscle generates lactate by anaerobic glycolysis. Lactate enters the blood stream and is taken up by the liver, which recycles it back to glucose through gluconeogenesis. This is known as the Cori cycle. Determine the energetic cost of maintaining glucose to the muscle by this mechanism. OPTIONS ARE: -6 -4 -2 0 +2 +4 +6 Pathway ATP generated ATP/GTP consumed Net ATP/GTP Glucose -> lactate Lactate -> glucose Net ATP/GTP
A suspension of yeast cells is being grown under anaerobic conditions such that glucose is degraded...
A suspension of yeast cells is being grown under anaerobic conditions such that glucose is degraded to ethanol and carbon dioxide. Adding an inhibitor of alcohol dehydrogenase to the yeast cell suspension results in rapid cell death. Why? a.) Without alcohol dehydrogenase, the acetaldehyde concentration increases to levels that are toxic to the yeast cells. b.) NADH generated during glycolysis cannot be recycled back to NAD+, thus anaerobic ATP production through glycolysis cannot be maintained. c.) Pyruvate is no longer...
