BIOMOLECULES AND ENZYMES

Detailed explanation-1: -All The 20 amino acids are classified into two different amino acid groups. Essential amino acids and Non-essential amino acids together make up the 20 amino acids. Out of the 20 amino acids, 9 are the essential amino acids, and the others are Non-essential amino acids.

Detailed explanation-2: -The human body uses just 21 amino acids to make all the proteins it needs to function and grow. Because amino acids can be arranged in many different combinations, it’s possible for your body to make thousands of different kinds of proteins from just the same 21 amino acids.

Detailed explanation-3: -The essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. The nonessential amino acids are alanine, asparagine, aspartic acid, glutamic acid, and serine.

Detailed explanation-4: -There are 22 amino acids that are found in proteins and of these, only 20 are specified by the universal genetic code. The others, selenocysteine and pyrrolysine use tRNAs that are able to base pair with stop codons in the mRNA during translation.

Detailed explanation-5: -The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
