Big Ideas from lesson 3
- Food (carbohydrates, proteins, and fats) has the capacity to provide the body with energy and building materials.
- Food molecules react with oxygen to provide energy to the cells of the body.
- Food molecules are similar in that they are all made of C, H, and O; and for proteins and carbohydrates, many subunits join together to form complex molecules.
- Fat molecules provide the body with more energy than carbohydrate and protein molecules because of their type, number, and arrangement of atoms.
- You have to exercise longer or harder to expend the energy that can be provided by fat than for the same mass of carbohydrates and proteins.
