Question

Which of the following is NOT an essential amino acid?

• A. Lysine
• B. Histidine
• C. Glutamine
• D. Methionine

Hint:

Answer 1

The Correct Option is C

Essential amino acids cannot be synthesized by the body and must be obtained from the diet.
- Lysine, Histidine, and Methionine are essential amino acids.
- Glutamine is a non-essential amino acid because the body can synthesize it. Thus, the correct answer is Glutamine.
