Question

Which of the following statements is not true? a. Essential nutrients can be synthesized by the body. b. Vitamins are required in small quantities for bodily function. c. Some amino acids can be synthesized by the body, while others need to be obtained from diet. d. Vitamins come in two categories: fat-soluble and water-soluble.

Short answer

a) Essential nutrients can be synthesized by the body b) Vitamins are required in small quantities for bodily function c) Some amino acids can be synthesized by the body, while others need to be obtained from diet d) Vitamins come in two categories: fat-soluble and water-soluble Answer: a) Essential nutrients can be synthesized by the body

Step-by-step solution

Statement a - Essential nutrients can be synthesized by the body

Essential nutrients are those that the body needs to function properly but cannot synthesize on its own. Thus, essential nutrients must be obtained from the diet. Hence, statement 'a' is False. #Step 2: Determine if the statement 'b' is True or False#

Statement b - Vitamins are required in small quantities for bodily function

Vitamins are organic compounds needed in small quantities in the diet because they cannot all be synthesized in the body. They play an essential role in various bodily functions like metabolism, immunity, and digestion. Therefore, statement 'b' is True. #Step 3: Determine if the statement 'c' is True or False#

Statement c - Some amino acids can be synthesized by the body, while others need to be obtained from diet

Amino acids are the building blocks of proteins. There are 20 amino acids needed by the body, out of which the body can synthesize 11. The remaining 9 amino acids, called essential amino acids, must be obtained from the diet. Hence, statement 'c' is True. #Step 4: Determine if the statement 'd' is True or False#

Statement d - Vitamins come in two categories: fat-soluble and water-soluble

Vitamins can be classified into two categories based on their solubility: fat-soluble vitamins (A, D, E, and K) and water-soluble vitamins (B-complex and C). This classification has functional implications in terms of absorption, storage, and excretion. Therefore, statement 'd' is True. #Step 5: Conclude the solution#

Conclusion

Based on the analysis of each statement, the only False statement is statement 'a' - Essential nutrients can be synthesized by the body. The correct answer to this exercise is option 'a'.
