Answer 1

The correct option is A Is synthesized in the body

There are 20 amino acids divided into two groups: essential and non-essential amino acids.

Essential amino acid includes arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine tryptophan and valine.

Non essential amino acids include: alanine, asparagine, asparatic acid, cysteine, glutamic acid glutamine, glycine, proline, serine and tyrosine.

Arginine and hisyidine are regarded as semi essential amino acids.

Non-essential amino acids are not commonly found in the diet, therefore, it is synthesised by our own body.

So, the correct option is 'is synthesized in the body'.
