Cellobiase is involved in the last step of the process of breaking down cellulose, a molecule made up of bundled long chains of glucose that are found in plant cell walls, to glucose. This is a natural process that is used by fungi to produce glucose as a food source. The natural substrate for the enzyme cellobiase is cellobiose.
