Question

Quizplus · Accepted Answer

Cellulose, found in high-fibre bread, is a complex carbohydrate that cannot be hydrolyzed by human digestive enzymes. Instead, it passes through the digestive tract largely undigested, providing bulk to aid in bowel movements. The other options listed, including fatty acids, starch, glucose, and fructose, are all digestible and can be hydrolyzed into more simple compounds for absorption into the body.
