Question

Relate the terms digestion, nutrients, molecules, waste, chemical reactions, and energy to one another in 2-3 sentences.

A) Digestion breaks down food into molecules and nutrients, which are then absorbed and used by the body in chemical reactions to produce energy. The waste products of digestion are eliminated from the body.
B) Digestion is the process of converting energy into chemical reactions, which release molecules and nutrients used for bodily functions. Waste is the byproduct of this process.
C) Nutrients are converted into energy through digestion and chemical reactions, leading to the creation of waste products and molecules.

Answer 1

Digestion is the process of breaking down food into nutrients, while absorption is the process that allows nutrients to be taken up by the blood.

Step-by-step explanation:

Digestion is the process of breaking down food into nutrients. There are two types of digestion, mechanical and chemical. In mechanical digestion, large chunks of food are broken down into small pieces. Mechanical digestion begins in the mouth and involves physical processes, such as chewing. This process continues in the stomach as the food is mixed with digestive juices. In chemical digestion, large food molecules are broken down into small nutrient molecules. This is a chemical process which also begins in the mouth as saliva begins to break down food and continues in the stomach as stomach enzymes further digest the food. Absorption is the process that allows substances you eat to be taken up by the blood.
