1. Assertion (A): Human diet should compulsorily contain Glycerine, Serine and Tyrosine.
2. Reason (R): Essential amino acids cannot be synthesised in the human body.
A
Both A and R are individually true and R is the correct explanation of A
B
Both A and R are individually true but R is not a correct explanation of A
C
A is true but R is false
D
A is false but R is true
Correct Answer: Option D
Explanation
1. Assertion (A) states that the human diet should compulsorily contain Glycerine, Serine and Tyrosine. This is false. Glycerine (Glycerol) is a component of fats and can be synthesized by the body. Serine and Tyrosine are amino acids, but they are considered non-essential amino acids because the human body *can* synthesize them (Serine from other metabolites, Tyrosine from the essential amino acid Phenylalanine). Therefore, they are not compulsory dietary components.
2. Reason (R) states that Essential amino acids cannot be synthesised in the human body. This is true. There are about nine essential amino acids (e.g., Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine) that the human body cannot synthesize in sufficient quantities (or at all) and must therefore be obtained from the diet.
3. Since Assertion (A) is false and Reason (R) is true, the correct option is D.
