Physiology 2130 Lecture Notes - Lecture 16: Catabolism, Blood Sugar, Pyruvic Acid
Document Summary
Metabolism is de ned as the chemical changes that occur within a cell to either manufacture energy, store energy, store energy, or build new cell structures. The two types of metabolism: anabolism: is the creation of large molecules from small ones with the use of energy atp, catabolism: is the breakdown of large molecules into small ones resulting in the release of energy atp. Triglycerides, which make up most of the fat found in the body, consist of three fatty acid chains attached to one molecule of glycerol. Proteins consist of long chains of amino acids linked together. Carbohydrates are long chains of monosaccharides joined together. Once in the body, some may partially reform while others stay as building blocks. These building blocks are circulating in the body and can be used to create new structures in the cell or to form atp, or they can be stored for later use.
