Quick Summary

Cellulase is an enzyme that breaks down cellulose, a complex carbohydrate and the main structural component of plant cell walls. While humans cannot digest cellulose, it is a vital food source for herbivores, as microorganisms in their digestive tracts produce cellulase to break it down. This enzyme is also found in some insects, like termites.12

Cellulase plays a crucial role in the breakdown of plant matter and is important in various industrial processes, including the production of biofuels and the processing of textiles. The study of enzymes like cellulase is fundamental to understanding biological and chemical reactions.234

Digestion
…for example, few animals possess cellulase (cellulose-digesting enzyme), despite the fact that cellulose constitutes much of the total bulk of the food ingested by plant-eating animals. Some nonetheless benefit from the cellulose in their diet because their digestive tracts contain microorganisms (known as symbionts) capable of digesting cellulose. The herbivores…
