Energy currency - Study guides, Class notes & Summaries

adenosine triphosphate (ATP) - energy currency of life, high energy molecule that stores energy we need to do anything. Universal unit of energy exhange NAD+, nicotinamide adenine dinucleotide - coenzyme in all living cells. Required for fundamental biological processes. Oxidized form active transport - requres energy. molecules move against concentration gradient. Ex. protein channels, endocytosis, exocytosis. Can be coupled to exergonic chemical reactions or exergonic movement of molecul...

energy Answer - the ability to do work, is everywhere in all systems, all of this comes from the sun or from food, ALWAYS conserved law of conservation of energy Answer - says that energy can be converted from one form to another, energy cannot be destroyed potential energy Answer - stored energy, includes the chemical energy available in biological molecules, batteries and gas kinetic energy Answer - energy of movement, includes light, heat or electricity kinetic energy, potential e...
