Explain the difference in energy yield between fat and glucose metabolism
?The breakdown of fat begins with beta oxidation, which breaks all of the fatty acids into two-carbon molecules. Unlike glycolysis where a single acetyl CoA is formed for every molecule of glucose, each of those 2-carbon chains from beta oxidation can be formed into a molecule of acetyl CoA. Most fatty acid chains range from 4-22 carbons, giving between 2 and 11 acetyl CoA molecules for every fatty acid that is broken down. The acetyl CoA then enters the TCA cycle, where it generates a number of electrons that can be used in the electron transport chain to generate ATP. The more acetyl CoA that are formed in fats leads to a much higher yield of ATP than the single acetyl CoA that is formed from glucose.
