Biosynthetic Metabolism

Previous chapters on the physiology of metabolism mainly considered the assimilatory and respiratory pathways of metabolism. This topic could also be called metabolic energy conversion. However, the processes of metabolism also encompass many synthetic processes which can only be discussed briefly here. Not only the growing plant but also the adult plant has to continuously rebuild many organic structures. As many molecules, e.g. RNA and enzyme proteins, are subjected to different rates of turnover (see p. 82), the plant must have active synthetic metabolism even if there is no net increase of material. Anabolic (synthesising) processes of metabolism are always endergonic, in contrast to catabolic (degradative) reaction pathways, i.e. they consume large amounts of photosynthetically or dissimilatory available free energy. Phosphate anhydrides, usually ATP, and reduction equivalents, usually NADPH, serve as energy carriers.
