See how I calculated ATP for glucose, follow that to calculate ATP for fructose. Remember, fructose ends up in acetyl coA but doesn't go through krebs cycle, instead gets tracked for fatty acid synthesis.therefore, We get low ATP In class, I mentioned that fructose is metabolized differently in the liver compared to glucose.Refer to the figure shown below to calculate the number ofATPs you would expect from the metabolism offructose in the liver.

You know that during oxidative phosphorylation, 1 NADH creates 2.5 ATP and 1 FADH2 creates 1.5 ATP. From this information, how many total ATP molecules will be produced from the complete oxidation of pyruvate?
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
