Answer 2

When the athlete runs for fifteen minutes primarily the carbohydrate macro-molecules break down in the body.  

Explanation:

• In a human body, carbohydrates are broken down first when energy is required and these serve as the primary source of energy.
• After the carbohydrates are depleted then the other macro-molecules of protein and fat are used to provide energy to the athlete for their continued run.
• It is crucial that athletes eat a balance of carbohydrates, proteins, and fats so that it has its required source of energy.
