Mitochondria are little organelles present within all cells of the human body. Mitochondria are often referred to as the “powerhouse of the cell” because they are responsible for producing most energy from food elements. They also contain all of the enzymes associated with aerobic energy production. These organelles are an important part of the metabolism because they control fat burning that occurs at low levels of exertion. The aerobic oxidation forms a large part of our basal metabolic rate so any increase in mitochondrial mass will help raise the metabolism.
