Question

Which of the following statements is false?

a. Minerals known to perform essential function include calcium, potassium, sodium, and chloride.
b. Nonessential amino acids are those not used in the synthesis of any human proteins.
c. Sodium is the mineral that is most common in ECF; it is important in osmosis, buffer systems and nerve impulse conduction.
d. Nutrients include water, carbohydrates, proteins, minerals and vitamins.
e. Fats soluble vitamins including vitamins A, D, E and K, are absorbed and stored with fats.

Answer 1

The false statement is 'b. Nonessential amino acids are those not used in the synthesis of any human proteins' because nonessential amino acids are used in protein synthesis but do not need to be obtained from the diet.

Step-by-step explanation:

The false statement among the options provided is b. Nonessential amino acids are those not used in the synthesis of any human proteins. This statement is incorrect because nonessential amino acids are indeed used in protein synthesis. They are termed 'nonessential' not because they aren't important, but because the body can synthesize them itself; they do not need to be obtained directly through the diet. Essential amino acids, in contrast, cannot be synthesized by the human body and must be obtained from food.

Regarding other options, minerals such as calcium, potassium, sodium, and chloride are important for various bodily functions including osmosis, nerve impulse conduction, and the hardening of bones. It is also true that nutrients include water, carbohydrates, proteins, minerals, and vitamins. Finally, fat-soluble vitamins like A, D, E, and K are indeed stored in the body alongside fats.
