What is the main source of energy of the human body?
Carbohydrates Abstract. Carbohydrates are the main energy source of the human diet. The metabolic disposal of dietary carbohydrates is direct oxidation in various tissues, glycogen synthesis (in liver and muscles), and hepatic de novo lipogenesis.
What are the 3 sources of energy for the body?
Energy comes from the three main nutrients carbohydrates, protein, and fats, with carbohydrates being the most important energy source. In cases where carbohydrates have been depleted, the body can utilise protein and fats for energy.
What is the body’s main source of energy quizlet?

What are the 6 main types of energy?
Energy comes in six basic forms: chemical, electrical, radiant, mechanical, thermal and nuclear. In other research, you may find additional forms mentioned such as electrochemical, sound, electromagnetic and others. However, many additional forms are combinations of these six basic categories.
Is protein the body’s main source of energy?
The body needs protein to maintain and replace tissues and to function and grow. Protein is not usually used for energy. However, if the body is not getting enough calories from other nutrients or from the fat stored in the body, protein is broken down into ketone bodies to be used for energy.
Which nutrients are sources of energy for the body?
Carbohydrates (starches and sugars), fat, and protein within food can all function as sources of energy when they are metabolized to carbon dioxide and water in respiration processes in all of our body's cells.
