Glucose can be made a number of different ways both naturally and manually. In plants it is made in the process of photosynthesis and it can also be made in a factory. Factory made glucose is used in many syrups and processed foods. It is made by chemically treating corn starch and then adding glucoamylase, which breaks down the sugar compounds so that the simple sugar, or glucose, is separate from the rest of the sugars. From here it is either liquidized or put directly into the food. In the human body the metabolism is in charge of turning the glucose into energy. When glucose is consumed from either natural or man made sources it is turned into energy or stored as fat. It does this by oxidizing the compound first which causes it to release carbon dioxide, water, and nitrogen compounds, which can then be used as energy by the cells. Lastly plants are able to make their own glucose through photosynthesis. They are the natural source and manufacturers of glucose. It is synthesized by the plant combining carbon dioxide and water in the chlorophil, which absobes light energy to fuel the reaction, with the chemical reaction:
6CO2 + 6H2O ---> C6H12O6 + 6O2
6CO2 + 6H2O ---> C6H12O6 + 6O2
