Energy metabolism is generally defined as the entirety of an organism's chemical processes. These chemical processes typically occur in the form of complex metabolic pathways within the cell, generally categorized as catabolic or anabolic. In humans, the study of energy flows and how energy processed in the body is termed bioenergetics. It is deal with the breakdown of macromolecules such as fats, proteins, and carbohydrates, to provide usable energy for growth, repair, and physical activity. Energy metabolism is the process of generating energy (ATP) from nutrients. Metabolism comprises a series of interconnected pathways that can function in the presence or absence of oxygen. Aerobic metabolism converts one glucose molecule into 30-32 ATP molecules. Fermentation or anaerobic metabolism is less efficient than aerobic metabolism.
