Chapter 26, Problem 1TYR

Summary Introduction

Introduction:

Nutrients are considered to give energy to the body by means of intake of carbohydrates, proteins, fats, vitamins, and minerals contained in food. Some nutrients cannot be synthesized from the human body; they only get it from the diet, and they are called as essential nutrients. Most of the micronutrients such as vitamins and minerals are considered as essential nutrients. These micronutrients are not used in giving energy to our body. It maintains the growth and regulation of our body.

Answer to Problem 1TYR

Correct answer:

Micronutrients are not used as fuel; they are required in relatively small quantities. Therefore, option a is the correct answer.

Explanation of Solution

Justify reasons for the correct statement:

Micronutrients are small quantities, required by the body for the maintenance of normal growth and regulation (such as vitamins and minerals).

Option (a) is given as, “Micronutrients”.

Micronutrients are used for the body in small amounts and are not considered as fuel substances. These are not involved in fuel for giving energy.

Hence, option (a) is correct.

Justify reasons for the incorrect statements:

Option (b) is given as, “Macronutrients”.

Macronutrients are used for the energy source of our body such as carbohydrates, fats, and proteins. Maximum quantities of macronutrients are required by the body. Hence, it is a wrong answer.

Option (c) is given as, “Essential nutrients”.

Essential nutrients are not produced in the body; they are consumed from the diet, which are necessary to our body for maintaining normal functions. Hence, it is a wrong answer.

Option (d) is given as, “Proteins”.

Proteins are macromolecules that are considered as body building components. These are made up of amino acids. Hence, it is a wrong answer.

Option (e) is given as, “Lipids”.

Lipids are the highest energy-giving products, which are made up of fatty acids and glycerol. Hence, it is a wrong answer.

Hence, options (b), (c), (d), and (e) are incorrect.

Conclusion

Micronutrients are utilized by the body in minor quantities and are mainly used for the regulation and growth of the body. They are not considered as fuel components of our body.
