Glucose by Nicole Glucose by Nicole One of the tasks of the digestive system is to break down starch-based carbohydrates such as potatoes and bread, into individal sugar molecules.
More amylase is mixed with food when it has passed down through the stomach into the intestine.
Amyase breaks the starch down into pairs of sugar molecules, which are then split by another series of enzymes in the small intestines, so that only individual sugar molecules are absorbed. Finally, the sugars are all carried to the liver in the bloodstream. The liver changes all the fructose and other similar compounds into glucose. The body has many mechanisms which make sure there is an adequate leval of glucose in the bloodstream to supply it's needs. When the glucose is inside the cells, it is burned with oxygen to produce energy.
