Respiration describes the metabolic process in cells that breakdown food molecules (glucose) and releases energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit...
