Cellular respiration: The breakdown of sugar (glucose) to form ATP (a form of energy for an organism). There are two types, aerobic and anaerobic (also called fermentation). History of Root Beer: Root beer was made by our forefathers by soaking Sasafras (a type of tree) root in water, and adding sugar and yeast (yeast for carbonation).
