In the process of making biofuel from corn, the corn is ground, mixed with water, and then enzymes are added to hydrolyze the starch into smaller sugar molecules. The fermentation produces ethanol and carbon dioxide. In a subsequent step, a microorganism ferments the sugars into ethanol and carbon dioxide. The ethanol is further distilled for use as a biofuel. In this process is an example of a chemical change.
