Document Summary

The totality of an organisms chemical reactions. Concerned with managing the material and energy resources of the cell. An organisms metabolism transforms matter and energy. Begins with specific molecule (substrate and reactant) and ends with a product. Each step is catalyzed by a specific enzyme. Release energy by breaking down complex molecules into simpler compounds. Cellular respiration, the break up of glucose in presence of oxygen. Consume energy to build complex molecules from simpler one. Is the study of how organisms manage their energy resources. Is the capacity to do work (cause change) Move matter against a force like gravity or friction, or biological work (growth, division, motility) Energy exists in various forms, some of which can perform work. Energy can be converted from on form to another. Energy associated with motion (energy of motion) Kinetic energy associated with random movement of atoms or molecules. Energy that matter possesses because of its location or structure (stored energy/energy of position)
