BIOL 1000 Chapter Notes - Chapter 4: Chemical Energy, Endergonic Reaction, Allosteric Regulation
Document Summary
Energy detected through ability to do work (not measured or weighed: defined: capacity to do work. Electromagnetic radiation (visible, infrared, and ultra-violet light) Through photosynthesis energy of light converted to chemical energy in the form of complex sugars & organic molecules. Kinetic energy energy posed by an object in motion: ex. Electricity (flow of electrons) / photons of light potential energy stored energy (location/chemical structure: arrangement of atoms in a molecule of glucose/gasoline (chemical potential energy) Thermodynamics study of energy and its transformations: system- object being studied. Isolated system one that does not exchange matter/energy with surroundings thermos. Closed system- can exchange energy but not matter with its surroundings: green house. Open system both energy and matter can move freely between system and surroundings: ocean absorbs and releases energy (hydrological cycle) evaporation and condensation, surroundings everything outside system, universe - total system and surroundings. 1 st law of thermodynamics transferred) but not created or destroyed principle of conservatio nof.
