Thermodynamics energy - capacity to do work kinetic energy - energy of motion potential energy - stored energy in objects not actively moving but w/ capacity to do so all energy can be converted into heat thermodynamics - "heat changes"; study of energy kilocalorie - unit of heat o equal to 1000 calories o 1 calorie needed to raise temperature of 1g water by 1 degree C o 0.239 calorie = 1 joule oxidation-reduction - energy stored as potential energy in covalent bonds strength of covalent bond measured by amount of energy needed to break it energy in bonds can transfer to new bonds during reactions oxidation - loss of an electron; oxygen (most common electron acceptor) takes the electron away reduction - gain of an electron redox reactions - chemical reactions w/ oxidation/reduction o oxidation/reduction must take place together o reduced form has higher energy level than oxidized form o reducing power - ability of organisms to store energy by transferring electrons
