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...

3. True or False [ ] In glycolysis, a single glucose molecule breaks down into two molecules of pyruvate, which can then be broken down further to release ATP. Glycolysis itself releases four net molecules of ATP per molecule of glucose. [ ] The main products in glycolysis include ATP, pyruvate and NADPH. [ ] In the preparatory phase of glycolysis, ATP is invested to convert glucose to fructose 1,6-bisphosphate. The bond between C-2 and C-3 is then broken to...

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.

9) Why store energy as fat? Determine the NET yield of ATP from the complete oxidation of one molecule of the fatty acid stearic acid (18:0) to Co, as compared to the complete oxidation of the 18 total carbons in 3 molecules of glucose. On an ATP/carbon basis, how much more efficient in percent), is the oxidation of fats than carbohydrates for providing energy to the cell? Show your work for each part.

1. If one (1) molecule of phosphonenol pyruvate is oxidized via glycolysis, the PDC, and the CAC in a kidney cell, how many protons are pumped into the inner membrane space at ETC Complex III? 2. If one (1) molecule of glyceraldehyde 3-phosphate is oxidized via glycolysis, the PDC, and the CAC in a skeletal muscle cell, how many protons are pumped into the inner membrane space at ETC Complex IV? 3. If two (2) molecules of pyruvate are oxidized...
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...
What is the net yield of ATP when Phosphoenolpyruvate is completely oxidized into CO2 via glycolysis,...
What is the net yield of ATP when Phosphoenolpyruvate is completely oxidized into CO2 via glycolysis, citric acid cycle and oxidative phosphorylation. Be sure to include ATPs produced by substrate level phosphorylations and oxidative phosphorylations coupled to reduced coenzymes. Please explain or show work, I don't understand how to answers these types of questions.
