Select the incorrect statement.
Options
- A'Hb' is an example of quaternary structure of protein.
- BIn the primary structure of protein, the left hand is C- terminal and the right hand is N-terminal.
- CIn protein or polypeptide, the amino acids are linked by peptide bond.
- DMost of the enzymes are protein in nature.
Correct answer
B. In the primary structure of protein, the left hand is C- terminal and the right hand is N-terminal.
Step-by-step solution
Most of the enzymes are proteins, except ribozymes which are made up of rRNA. Hb, Haemoglobin is made up of four polypeptide chains, 2 alpha, and 2 beta chains. In a polypeptide, amino acids are linked by the peptide bond in which the first amino acid towards the left hand represents the N-terminal end, and the last amino acid towards the right hand represents the is C-terminal end.
