Document Summary

In topics 9-12 we have looked at the major pathways involved in human energy metabolism. These pathways show how different types of biomolecule contribute to atp production (i. e. , provide energy to the cell). Fats provide atp via fatty acid -oxidation (and similar pathways for lipids other than fatty acids), followed by the citric acid cycle and oxidative phosphorylation. Carbohydrates are broken down via glycogen or starch degradation and glycolysis, followed by the citric acid cycle and oxidative phosphorylation. Proteins are degraded to amino acids, which feed into energy metabolism as intermediates in glycolysis and the citric acid cycle. The energy content of food is normally expressed in calories (note the capital c; also called dietary calories, food calories, kilogram calories, or large calories). One calorie equals 1000 calories (also called gram calories or small calories). One calorie is the amount of energy needed to raise the temperature of one gram of water by one degree.
