BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Amino acids have two functional groups in a molecule. They react by condensation polymerisation to produce polypeptides. Different amino acids can be combined in the same chain to produce proteins. essential for life.

Detailed explanation-2: -Amino acids all have very similar physical properties. This statement is false. The physical properties of Amino Acids vary considerably.

Detailed explanation-3: -Translation: The process of polymerisation of amino acids to form a polypeptide chain is called translation. During the translation process, the genetic information stored in mRNA directs the order of amino acids to form a polypeptide chain. Ribosomes along with tRNA also participate in the process of translation.

Detailed explanation-4: -All other amino acids contain four different groups. Hence all other amino acids are optically active. Therefore the correct statement is, all amino acids except glycine are optically active.
