Question

Quizplus · Accepted Answer

Cellulase is an enzyme that breaks down cellulose, a complex carbohydrate found in plant cell walls. Cows have a specialized stomach chamber called the rumen where cellulose digestion occurs, facilitated by microbes that produce cellulase. Humans do not have this specialized chamber or the ability to produce cellulase in their stomachs. Therefore, the presence of cellulase in the stomach sample would indicate that it came from a cow.
