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

Answer 1

An enzyme is a substance that helps in the chemical digestion of food. Enzymes are biological catalysts that speed up chemical reactions in the body, including the breakdown of food molecules into smaller, more easily absorbable components. Examples of enzymes involved in the digestion of food include amylase, which breaks down carbohydrates, lipase, which breaks down fats, and protease, which breaks down proteins.
