Energy: Photosynthesis and Respiration
Subject:
Biology [1]
ENERGY Physiology Function:worklive -grows(mitosis) -reproduce(meiosis+fertilization) -metabolism(photosynthesis and respiration) -inheritance(generation) Definition of Energy 2 Laws of Energy: 1.Conservation of Energy- energy is neither created nor destroyed, only transformed(1st law) *forms of energy: solar, potential, mechanical 2.Entropy- during the transformation of energy, some energy become disordered & becomes heat(2nd law) *heat: ?disordered energy? Coupled Reactions and Chemical Bonds *?coupled?: with partner *coupled reactions= redox reactions 1.Reduction- gains electrons -creates chemical bond -stores energy in molecule -Photosynthesis(anabolic) 2.Oxidation-loses electrons
