yielding metabolism in aerobic organisms. All oxi￾dative steps in the degradation of carbohydrates, fats, and amino acids converge at this final stage of cellular respiration, in which the energy of oxidation drives the synthesis of ATP. Photophosphorylation is the means by which photosynthetic organisms capture the energy of sunlight—the ultimate source of energy in the bio￾sphere—and harness it to make ATP. Together

he third and final part of this book explores the bio￾chemical mechanisms underlying the apparently con￾tradictory requirements for both genetic continuity and the evolution of living organisms. What is the molecular nature of genetic material? How is genetic information transmitted from one generation

solar energy as the driving force for this global process (Fig. 1). All living organisms also require a source of nitro￾gen, which is necessary for the synthesis of amino acids, nucleotides, and other compounds. Plants can generally use either ammonia or nitrate as their sole source of ni￾trogen, but vertebrates must obtain nitrogen in the form
