Answer 1

(d) Assertion is false, but reason is true. Essential amino acids are those which are taken form food and not synthesised in the body, whereas non-essential amino acids need not be supplied in the diet and synthesised in the body. Glycine serine and tyrosine are non-essential amino acids.
