Which of the following organic compounds is the richest source of energy?
Fat
Carbohydrates
Proteins
Food supplies us with the matter necessary to build living tissue and the energy to do work. There are three main types of macromolecules found in the food we eat; carbohydrates, lipids and protein. Food also contains vitamins and minerals, but we are not concerned about those during this activity. Each of these types of macromolecules vary in structure and function and they also store different amounts of energy.
