Question

E. Answer these questions.
1. What happens to the food in the mouth?
​

Answer 1

Answer:

In the mouth, the food is chewed and broken down into a form that can be easily digested. It is then mixed with saliva that softens the food and kills bacteria that may be present. It also contains the enzyme salivary amylase that breaks down starch into its monosaccharide units, maltose.

Answer 2

Answer:

Food enters the digestive system through the mouth. Food is broken down into smaller pieces by chewing. The teeth cut and crush the food, while it's mixed with saliva. This process helps to make it soft and easier to swallow.
