Explanation:
Detailed explanation-1: -We store it in big blobs called glycogen that can hold 30, 000 glucose molecules. Building up glycogen is the basis for carbo loading or carbing up. That’s when runners eat loads of carb heavy meals, cramming as much glucose into their cells in the days before a race.
Detailed explanation-2: -The organic molecules that store the most energy are called fats or triglycerides. The animal body uses carbohydrates (glycogen) for medium-term energy storage and fats or triglycerides (lipids) for long-term energy storage.
Detailed explanation-3: -1. Why would a distance runner consume carbohydrates instead of proteins before a race? Carbohydrates provide insulation for heat.
