Energy & Exercise Metabolism

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. The syndrome is thought to be caused by an underlying disorder of energy utilization and storage. Muscle cells need a lot of energy, which means they burn a lot of calories. In fact, they burn more calories than fat cells, even when you're not exercising. So the time you spend working out reaps benefits long after you stop sweating. Exercise becomes even more important as you get older. You naturally lose muscle mass with age, which slows down your metabolism.
