AP BIOLOGY

Detailed explanation-1: -Fats: Triglycerides make up more ATPs because they have three fatty acid tails connected to glycerol and they give additional energy.

Detailed explanation-2: -When compared to other macronutrient classes (carbohydrates and protein), fatty acids yield the most ATP on an energy per gram basis, when they are completely oxidized to CO2 and water by beta oxidation and the citric acid cycle.

Detailed explanation-3: -The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.

Detailed explanation-4: -Lipid oxidation provides more ATP than carbohydrate, but it requires more oxygen per mole of ATP synthesized. (II) The ratio of NADH oxidation versus FADH, oxidation depends on the proton motive force, and lowering proton motive force by uncoupling favours FADH2 oxidation, i.e. lipids versus carbohydrate.

Detailed explanation-5: -Posted July 19, 2022. More than one hundred ATP molecules can be generated from the complete oxidation of one molecule of fatty acid. The exact number of ATP molecules generated depends on the number of carbon atoms in the fatty acid that is being oxidized.
