Eukaryotic cells include a plurality of organelles uncommon by means of their particular membranes and contents. Their biogenesis happens through development and department of preexisting constructions instead of de novo. Mitochondria and chloroplasts, which seem to be descended from prokaryotic ancestors, have retained a few DNA and the biosynthetic potential for its expression.

For a gaseous mixture, in addition to the molar fraction x~, two other concentration units may be used: One is the partial pressure Pi = x~p, which is proportional to the molar fraction x~ and the total pressure p; and the other is the molar concentration (molafity) c~ = ni/V, which is inversely proportional to the volume V of the gaseous mixture. In terms of these concentration units the equilibrium constant of a gas reaction is expressed in three different formulas shown, respectively, in Eq.
31) Cp, i d W . The double integral may be transformed by integration by part to Eq. 32: --TT- c p, i d T = dT --T-- d T = ---if- d T - cp, i dT. 32) Thus, Eq. 33) With the aid of tables of molar heat capacities in physicochemical handbooks we can evaluate the third term on the right hand side of this equation for each constituent substances taking part in the reaction. CHAPTER 5 CHEMICAL POTENTIAL The chemical potential is defined as an intensive energy function to represent the energy level of a chemical substance in terms of the partial molar quantity of free enthalpy of the substance.
3 in Eq. 2 then gives Eq. 4) Since A - 0 at equilibrium, Eq. 4 yields Eq. 5 when the reaction is at equilibrium: K(T, p ) - a'(~a~2 a~3 a~4. 5) We call K(T, p) the equilibrium constant of the reaction. As realized from Eq. 2, the reaction equilibrium is established at which the unitary affinity A* becomes equal to minus the affinity of mixing A M of the reaction. 3 kPa, and unit activities) is normally called the standard affinity A ~ 6. 2. The Unitary Affinity. From Eq. 3 we have the relation between the unitary affinity A* and the equilibrium constant K( T, p) of a reaction as shown in Eq.
