Food contains large, complex molecules that cannot be easily absorbed into the body and used by cells. Bread, for example, contains starch, which is a polysaccharide. Digestive enzymes break down these complex molecules into smaller molecules the body can use. What would happen if digestive enzymes were not present?

Digestive enzymes are the enzymes that function in the breakdown of complex food molecules into smaller molecules that can be easily utilized by the body.

If digestive enzymes were not present in our system, the complex food would be unable to break down into simpler molecules and the undigested food will move down into the large intestine, causing unpleasant symptoms such as gastric. The absence of digestive enzymes can also reduce the energy and nutrients components in the body.
