BIOL 1000 Chapter Notes - Chapter 4: Covalent Bond, Enzyme Inhibitor, Futile Cycle
Document Summary
Energy is detected through its ability to do work, move object against opposing forces. Energy the capacity to do work (friction, gravity, pressure) 4. 1a- energy exists in different forms and states. Energy exists in diff. forms (heat, chemical, electrical, mechanical) Energy can be transformed from one form to another. All forms of energy belong to one of the two states: kinetic or potential. Kinetic energy energy possessed by an object b/c it"s in motion (waves, photons of light, flow of electrons) Potential energy stored energy- energy an object has b/c of its location and chemical structure (chemical potential energy) 4. 1b- the laws of thermodynamics describe the energy flow in natural. Thermodynamics the study of energy and its transformations. System the object being studied in thermodynamics (cell, earth, a molecule) There are 3 types of systems: isolated, open , and closed. Closed system exchange energy but not matter with its surroundings. Open system-> exchange both energy and matter with its surroundings.
