Final answer:
The statement is TRUE as the different structures of carbohydrates in broccoli and donuts mean they are digested differently by the body. Carbohydrates start digesting in the mouth and continue in the small intestine, where they're finally broken down into glucose for energy. Dietary fiber, a component of carbs, has multiple health benefits but is not used for energy.
Step-by-step explanation:
Broccoli and donuts may contain the same total amount of carbohydrates, but their structures are different. Hence, the body digests these carbohydrates differently, making statement A) TRUE. Carbohydrates digestion begins in different parts of the digestive system, with each type being processed in specific areas.
The digestion of carbohydrates starts in the mouth where the enzyme amylase breaks down starch into simpler sugars. This process continues in the small intestine where further enzymatic action converts these sugars into glucose. Glucose is then utilized in cellular respiration to produce ATP (energy currency of the cell).
Dietary fiber, mostly cellulose, is part of carbohydrates that is not digested for energy but has essential roles such as promoting regular bowel movements, regulating blood glucose levels, and aiding in the removal of excess cholesterol from the body.
In summary, a well-balanced diet includes carbohydrates supplemented with proteins, vitamins, and fats. Carbohydrates not only provide a source of energy but also contribute to overall health through their soluble and insoluble elements.
