Concept explainers
_____ 1. Which of the following is a nutrient?
- a. proteins
- b. minerals
- c. vitamins
- d. All of these are correct.
Introduction:
The body requires a definite amount of essential nutrients for proper growth and development of the body. The body also stores nutrients for situations when a body does not get nutrients.
Answer to Problem 1DYKB
Correct answer:
The vitamins, proteins, and minerals are all nutrients. Therefore, option d. is correct.
Explanation of Solution
Reason for the correct statement:
Option d. is given as “All of these are correct”. The amino acids are the building blocks of macromolecules proteins. There are twenty amino acids required to make proteins in all organisms. These proteins participate in the metabolism of organisms. The organic molecules required for efficient functioning of enzymes in the metabolism of organisms are called vitamins. There are thirteen known important vitamins in animal metabolism. The inorganic chemical entities including phosphorus, iron, zinc, and many more are considered as minerals. They are needed in same amounts in the body. They perform diverse functions in the body. Hence, the nutrients include vitamins, proteins, and minerals.
Hence, option d. is correct.
Reasons for incorrect statements:
Option a. is given as “proteins”.
The amino acids are the building blocks of macromolecules proteins. There are twenty amino acids required to make proteins in all organisms. These proteins participate in the metabolism of organisms. The vitamins and minerals are also considered as nutrients. Hence, option a. is incorrect.
Option b. is given as “minerals”.
The inorganic chemical entities including phosphorus, iron, zinc, and many more are considered as minerals. They are needed in same amounts in the body. They perform diverse functions in the body. The proteins are also included in nutrients. Hence, option b. is incorrect.
Option c. is given as “vitamins”.
The organic molecules required for efficient functioning of enzymes in the metabolism of organisms are called vitamins. There are thirteen known important vitamins in animal metabolism. The proteins are also included in nutrients. Hence, option c. is incorrect.
Hence, options a., b., and c. are incorrect.
The nutrients are needed by the body for maintaining homeostasis. The proteins, vitamins, and minerals are included in nutrients.
