The development and evolution of all species can, in many ways, be traced to a few biochemical reactions that facilitate metabolic and/or photosynthetic changes in each life form. Indeed, advances in the field of biochemistry have intimately depended on the study of these processes and the way basic molecules fragment and synthesize to produce elements vital to the survival of each organism. This insightful volume considers the various types, causes, and results of different reactions that operate at the cellular level and beyond to sustain biological activity.
