Question

The first enzyme to mix with food in the digestive tract is ______.

Options

• pepsin

• cellulose

• amylase

• trypsin

Answer 1

The first enzyme to mix with food in the digestive tract is amylase.

Explanation:

The digestion process begins immediately in the mouth (buccal cavity). As you chew food, the salivary glands secrete saliva containing salivary amylase, making it the very first enzyme to mix with food in the digestive tract. It immediately breaks down complex starches and carbohydrates into simpler sugars like maltose.
