Biochemistry asks how the remarkable properties of living organisms arise from the thousands of different lifeless biomolecules. When these molecules are isolated and examined individually, they conform to all the physical and chemical laws that describe the behavior of inanimate matter—as do all the processes occurring in living organisms. The study of biochemistry shows how the collections of inanimate molecules that constitute living organisms interact to maintain and perpetuate life animated solely by the physical and chemical laws that govern the nonliving universe.Principles of Bioenergetics/BiochemistryThe total energy of the universe is constant (能量守恒定律);The total entropy(熵) is continually increasing（熵增加原理）.—Rudolf Clausius, The Mechanical Theory of Heat with Its Applications to the Steam-Engine and to the Physical Properties of Bodies,1865 (trans.1867)ATPFrom Petras P.
