Quizplus · Accepted Answer

Carbohydrates are the nutrient that provides the major energy source during exercise. When carbohydrates stored in the muscle and liver are broken down into glucose, it is converted into ATP, which is the primary energy source for muscle contractions during exercise. While protein and fat can also be used for energy, they are less efficient than carbohydrates and are usually only used when carbohydrate stores are depleted. ATP is the energy currency of cells, but it is not a nutrient that can be consumed in food.
