Keeping this in view, where does the body get energy from?
This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
Herein, what is the body's main source of energy quizlet?
your body converts all carbohydrates to glucose ( which is a simple sugar that is the body's main source of energy). glucose that is not used right away is stored in the liver and muscles as glycogen. when more energy is needed glycogen is converted back to glucose.
Our muscles are primed to burn fat, and it is our most concentrated form of energy. When we begin to exercise, we burn glucose and glycogen, but it only takes a matter of minutes to shift to fat.
