Organisms are energy transformers!Catabolism- cellular respiration- sugar put in to the body is broken down to do work in the cell (movement, active transport, etc). Energy released (helps to drive anabolic pathways). Anabolic- sometimes called biosynthetic pathways- synthesis of a protein from amino acids. Energy required/absorbed. Bioenergetics- the study of how energy flows through living systems. Energy- the capacity to cause change. Some forms of energy can be used to do work- or move matter against opposing forces (friction and gravity)Kinetic Energy- moving objects can perform work by imparting motion to other matter. Moving water through a dam turns turbines, moving bowling ball knocks over pinsHeat/Thermal Energy- comes from the movement of atoms or molecules associated with kinetic energyPotential Energy- because of location or structure, height, chemical bonds, etc.Chemical- the potential energy available for release by a reaction. Glucose is high in chemical energy and the process of glycolysis breaks it down. As bonds are broken, energy is released, but bonds also reform to make new molecules, thus it uses some energy. Net release, thus ANABOLIC OR CATABOLIC???

Organisms are energy transformers! All original energy comes from light. (photosynthesis- primary producer- consumer- who changes it from chemical to kinetic and releases thermal.2Metabolism and EnergyMetabolismMetabolic pathway begins with a specific molecule, which is then altered in a series of defined steps leading to a specific productEach step is catalyzed by a specific enzymeOrganisms are energy transformers!Catabolism- cellular respiration- sugar put in to the body is broken down to do work in the cell (movement, active transport, etc).
