This live review discusses the role and importance of Bioenergetics and Biological Oxidation in the different metabolic processes that the various macromolecules undergo.
Bioenergetics is the study of the energy changes that accompany chemical reactions. Metabolism which is the sum total of all the biochemical processes within the body consists of different energy utilizing and energy liberating reactions. In metabolism, metabolic fuel is utilized through biological oxidations and the energy produced from such reactions may be utilized to drive the energy-requiring reactions.
