Question

Quizplus · Accepted Answer

Carbohydrates and fats contain many electrons associated with hydrogen atoms. These electrons are available for oxidation reactions, which release energy that can be used by the body for various metabolic processes. This is why carbohydrates and fats are considered high-energy foods.

Note: Options A and B are incorrect because the presence or absence of oxygen and nitrogen atoms has no direct relationship with energy content. Option D is also incorrect because carbohydrates and fats are not strong oxidizing agents themselves, but rather provide energy through oxidation reactions with other molecules.
