Study Notes
Carbohydrates, Fats, and Proteins
- Carbohydrates provide energy to the body by breaking down into glucose, which fuels cells.
- Protein helps the body grow and repair, and is involved in making red blood cells (haemoglobin) and antibodies.
- Fats and oils provide energy and are necessary for making cell membranes; they differ in that fats are solid at normal temperatures, while oils are liquid.
Energy Stores
- Energy from carbohydrates and fats is stored in the body in two ways: short-term and long-term.
- Short-term energy stores are located in cells, particularly in the liver and muscles.
- Long-term energy stores are found in body fat, which is stored under the skin and around organs.
- Fat stores help regulate body temperature, like in seals living in cold environments.
Food Sources
- Protein-rich foods include fish, meat, eggs, nuts, and beans.
- Foods rich in starch include corn, potatoes, rice, bread, and pasta.
- Foods high in fat include oil, butter, cheese, and meat.
