Question

Which of the following amino acids is not necessary to be taken in the diet?

• A. \( \text{Histidine} \)
• B. \( \text{Threonine} \)
• C. \( \text{Serine} \)
• D. \( \text{Lysine} \)

Hint:

Non-essential amino acids can be synthesized from metabolic intermediates, whereas essential amino acids must be supplied through food.

Answer 1

The Correct Option is C

Serine is a non-essential amino acid, meaning it can be synthesized by the human body. In contrast, histidine, threonine, and lysine are essential amino acids and must be obtained through diet. Serine plays a vital role in cellular metabolism, protein synthesis, and neurotransmission.
