In growing children, the conditionally amino acids are termed as essential amino acids. Which of the following describes the same? P. Cysteine
Q. Arginine
R. Serine

In our diet, those amino acids which are not synthesized in our body and take in the form of diet (food) are termed as as essentially amino acids. Cysteine and Arginine are come in the class conditionally amino acids. However, cysteine, a sulphur-containing amino acid, tyrosine and arginine are required by infants and growing children. In the cases, these amino acids are termed as essential amino acids and required in the diet besides of conditionally amino acids.Hence, both P and Q are termed as essentially amino acid in case of growing children.
