Question

parents have long told their children to thoroughly chew food before swallowing. use what you know about the factors affecting chemical reaction rates to explain why chewed food is digested faster than unchewed food

Answer 1

The chemical process of digestion begins with chewing.Food's contact with saliva is important because it helps to lubricate the food, making it easier for foods (notably dry ones) to pass easier through the esophagus. It's also important because saliva contains enzymes that contribute to the chemical process of digestion.

Carbohydrate digestion begins with salivary alpha-amylase secreted by glands positioned near the mouth. This alpha-amylase helps break down some of the chemical bonds that connect the simple sugars that comprise starches. Additionally, the first stage of fat digestion also occurs in the mouth with the secretion of the enzyme lingual lipase by glands located at the root of the tongue.

in addition, When food is chewed it is broken down into smaller particles, creating a greater surface area. Thus more surface area is exposed to the chemicals for digestion
