Question

Quizplus · Accepted Answer

Fat is the largest potential energy store in the body, containing more than twice as much energy per gram as either carbohydrate or protein. It is stored primarily in adipocytes (fat cells) and can be utilized as a fuel source during extended exercise, fasting, or periods of low carbohydrate intake. Blood glucose and muscle glycogen provide more immediate sources of energy, while protein is primarily used for tissue repair and other metabolic functions.
