Quizplus · Accepted Answer

When a person is at rest or not active, the main source of fuel is fatty acids, which are stored in adipose tissue and can be broken down and used for energy. Glucose is used as a fuel source during exercise or when the body's demand for energy is high, but during rest or low activity levels, fatty acids are the primary source of fuel. Protein is not an efficient source of fuel and is only used as a last resort when the body does not have enough glucose or fatty acids available. Creatine phosphate is a molecule that helps regenerate ATP, the body's energy currency, but it is not a primary fuel source.
