Cellulases catalyze the decomposition of cellulose into smaller sugar units like glucose. This is a multi-step process involving three types of cellulases: endoglucanases, exoglucanases, and β-glucosidases. Endoglucanases cut the internal bonds of the cellulose chain, exoglucanases remove cellobiose units from the ends of the cellulose chain, and β-glucosidases hydrolyze cellobiose into glucose.
