Document Summary
Essential biochemistry - 3rd edition - charlotte w. pratt and kathleen cornely. Cells require energy for all the functions of living, growing and reproducing. As such, assembling monomers into polymers requires energy. Thermodynamic terminology is used to describe the energy in biological systems. All organisms are subject to the laws of thermodynamics. While organisms can transform energy, they cannot create or destroy energy! Enthalpy and entropy are components of free energy: Gibb"s free energy (g) or just free energy is used to describe energy in biochemical systems. Can be thought of as the measure of the system"s randomness or disorder, because the more ways the system can be arranged, the more dispersed its energy. Free energy, enthalpy and entropy are related to each other in the following equation: Temperature is the coefficient of entropy, because entropy varies with temperature. Entropy of a substances increases when its temperature is increased because more thermal energy has been dispersed within it!
