-is a substance that helps in the chemical digestion of food

Answer 1

There are several substances that help in the chemical digestion of food. One important substance is enzymes. Enzymes are proteins that speed up chemical reactions in the body. They play a crucial role in breaking down macromolecules such as carbohydrates, proteins, and fats into smaller molecules that can be easily absorbed and used by the body. Examples of digestive enzymes include amylase, lipase, and pepsin. These enzymes are produced by various organs in the digestive system, such as the salivary glands, stomach, pancreas, and small intestine, and they help break down food into simpler forms that can be readily absorbed by the body.
