When you eat, the enzymes in your mouth, called Amylase (1), immediately begin to attach themselves to the sugar that is in your food called Amylose. Amylose is a substrate (2) that the enzyme Amylase bonds to creating a lock and key model (3). The enzyme helps the amylose by lowering the activation energy needed to break it down and by making the breakdown of the sugar occur faster. This reaction yields (4) fructose and galactose as monosaccharides (5).
