Lecture 9: Energy Metabolism 2/22/10 From Food to Energy Carbs to glucose (4 kcal/g) Fats to fatty acids (9 kcal/g) Proteins to amino acids (4 kcal/g) All 3 combined in metabolic pathways to form ATP (energy source for body functions) Metabolism sum of all chemical & physical process by which body breaks down & build molecules to get metabolic pathways are chemical rxns that happen to break down a macromolecules for energy Our body vs. Bomb Calorimeter Bodily “calorimetry” is more controlled and does not have a complete combustion. The bomb calorimeter does NOT tell how efficiently out bodies use food. ATP contains high energy phosphate bonds that are broken Carbs to Glucose to Liver Whole grain bread is about 52% carbs fats of liver glucose: converted to glycogen metabolized for energy or used to make other glucose containing compounds
