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.
Learn how different food groups like carbohydrates, proteins, and fats contribute to our body's energy and overall health. Discover their roles in producing energy, growth, and repair.
