Explanation:
Detailed explanation-1: -During the process of digestion, the food is broken down into smaller molecules. The salivary glands present in our mouth help in the breakdown of the food. In this process, there is a formation of a new substance. Therefore, it is considered to be a chemical change.
Detailed explanation-2: -The major types of enzymes involved in the chemical digestion of food are protease, amylase, and lipase. Protease digests proteins into amino acids while amylase digests carbohydrates into simple sugars and lipase breaks down lipids into fatty acids.
