Document Summary

Fats, carbs, and proteins are used for energy or to build structures. Metabolism is defined as the chemical changes that occur within a cell to either manufacture energy, store energy, or build new cell structures. The energy molecule used by the body is called atp. Two types of metabolism: anabolism is the creation of large molecules from small ones with the use of. Atp: catabolism is the breakdown of large molecule into small ones resulting in the release of atp. Triglycerides make up most of the fat found in the body and consist of three fatty acid chains attached to one molecule of glycerol. Proteins consist of long chains of amino acids linked together, and carbs are long chains of monosaccharides joined together. Once in the body, some of these larger molecules may partially reform while others stay as building blocks.
