Document Summary
Energy metabolism: the pathways involved in the generation or storage of metabolic energy. We get it from fuel , and that fuel comes from our diet or fuel reserves in our body. Stored in the body for energy except for protein carbohydrates (also known as sugars) lipids (also known as fats) Lipids: three fatty acids are esterified with a molecule of glycerol to form a triglyceride, which is how the body stores lipids. Glucose molecules are linked together to form a very large molecule of glycogen, which is how the body stores carbohydrates. Preferred fuel is glucose - especially at high intensity exercise. At low intensity exercise or rest - satisfied with lipids. As mentioned, the body does not store" protein in a way that is analogous to lipid and carbohydrate storage. Under periods of prolonged starvation, the body will draw on the protein found in muscle as energy.
