Document Summary

Chemical reactions that convert molecules into other molecules and transfer energy in organisms. Breakdown of molecules into smaller units, producing. Building of molecules from smaller units, requiring an input of energy, atp. Form of potential energy held in chemical bonds between pairs of atoms. Strong bonds have less potential energy than weak bonds. Weak bonds contain a lot of chemical energy. *likelihood of bond breaking and giving up energy. Bonds linking phosphate groups have high potential energy. Energy is neither created nor destroyed, it simply changes form. Energy available to do work decreases, entropy (disorder) increases. Energy is often in form of heat used to increase entropy. Number of possible positions and motions a molecule can take on in a given system. Most entropy increase occurs through transformation of energy into thermal energy (heat) A, b are reactants in forward reaction. C, d are products in forward reaction. C, d are reactants in reverse reaction.
