Question

Answer 1

Answer:

The nutrients that provide energy are commonly referred to as macronutrients (carbohydrates, lipids, and proteins). Carbohydrates and proteins provide a similar amount of energy per gram of

Answer 2

Explanation:

Protein is the main constituent of the body, making up the muscles, internal organs, skin, and blood, etc. If compared to a car, it would be the material from which the body and engine are made. Just like a car cannot be driven fast without a solid frame, without protein the human body cannot be kept in a healthy state. There are 20 kinds of amino acids that make up proteins, 9 of which are not synthesized in the body, and are therefore called essential amino acids. These essential amino acids must be supplemented from meals.

Carbohydrates can be broken down further into the two categories of sugars and dietary fiber. Sugars are the carbohydrates which can be used as an energy source to move the body (such as during exercise) and are stored in the liver and muscles as glycogen. Sugars are also the main source of energy for the brain.

Vitamins and minerals are not used as energy, but instead aid in breaking down and building up proteins, fats, and sugars, and are an essential nutrient for keeping the body healthy and in good working order. “Vitamin” is the general term for the organic compounds (compounds containing carbon) which are mostly impossible for the body to synthesize, and a lack of these vitamins can possibly lead to various deficiency-related diseases.
