3. Humans produce the enzyme amylase. This enzyme breaks down starch, a complex carbohydrate found in many food sources. Explain why the human digestive system is unable to use amylase to break down the complex carbohydrate cellulose, which is found in some foods. O The enzyme doesn't fit into the substrate. O The substrate doesn't fit into the enzyme. OAmylase gets denatured when encountering cellulose. O Humans who can't break down cellulose are allergic to it.
