Document Summary
Metabolism = chemical changes that occur within a cell to either manufacture energy, store energy, or build new cell structures. Energy molecule used by the body is called adenosine triphosphate [atp] Anabolism = creation of large molecules from small ones with the use of energy [atp] Catabolism = breakdown of large molecules into small ones resulting in the release of energy [atp] Triglycerides = 3 fatty acid chains attached to 1 glycerol: fats are stored as triglycerides inside fatty tissue called adipose tissue. Proteins = long chains of amino acids linked together: amino acids become structural or functional proteins inside the muscle cells. Carbohydrates = long chains of monosaccharides [glucose] joined together: stored inside muscle and liver cells in the form of glycogen. These building blocks may partially reform while others stay as building blocks. These building blocks circulate in the body and can be used to create new structures in cell or to form.
