Question

Digestion is the breaking down of large food molecules into smaller ones. The main purpose of this is

• A. Make the food soluble
• B. Enable the digestive enzymes to be used up
• C. Provide molecules which can be easily absorbed
• D. Make the passage of the food along the gut easier

Answer 1

The correct option is C Provide molecules which can be easily absorbed

Most of our nutrients contained in the food have a complex structure. In order to be absorbed and utilized by the body, they must be broken down into relatively simple molecules. The process by which the complex food molecules are changed to simple molecules is called digestion.
