Read the following passage to answer the following questions:
Proteins are polypeptide chains made up of amino acids. There are 20 types of amino acids joined together by peptide bond between amino and carboxylic group. There are two kinds of amino acids, Essential amino acids and Non-essential amino acids. The Primary structure of protein is the linear sequence of amino acids in a polypeptide chain. The first amino acid of sequence is called N-terminal amino acids and last amino acid of peptide chain is called C-terminal amino acids. The secondary structure proteins forms helix. There are three types of secondary structure: a helix, P pleated and collagen helix. In tertiary structure long protein chain is folded upon itself like a hollow woollen ball to give three-dimensional view of protein. In quaternary structure, each polypeptide develops its own tertiary structure and function as subunit of protein.
Q. There is extensive diversity of protein molecules is due to
  • a)
    NH2 - group of amino acid
  • b)
    R - group of amino acid
  • c)
    COOH- group of amino acid
  • d)
    Sequence of amino acids
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Read the following passage to answer the following questions:Proteins...
Protein is a polypeptide chain made up of amino acids. The amino acids consist of amine group (NH2-) and the carboxyl group(COOH-) at the end and a side chain of R- group which is specific to a particular amino acid. This specific group brings a variability to the proteins e.g, if R group is H it is glycine while if it is CH, It is alanine. The sequence of amino acids determines the protein. Therefore, diversity of protein molecules is due to the different sequence of amino acids linked with the protein molecules.

Sequence of amino acids
Proteins are composed of long chains of amino acids linked together by peptide bonds. The sequence in which these amino acids are arranged plays a crucial role in determining the structure and function of the protein. Here's why the extensive diversity of protein molecules is primarily due to the sequence of amino acids:

Variety of amino acids
- There are 20 different types of amino acids that can be combined in various sequences to form a wide range of proteins.
- Each amino acid has its own unique side chain (R-group) which contributes to the overall structure and function of the protein.

Primary structure
- The primary structure of a protein refers to the specific sequence of amino acids in the polypeptide chain.
- Even a small change in the sequence of amino acids can result in a completely different protein with distinct properties.

Secondary and tertiary structures
- The sequence of amino acids determines how the protein folds into secondary structures such as alpha helices or beta sheets.
- The tertiary structure, which is the three-dimensional arrangement of the protein, is also influenced by the sequence of amino acids.

Functional diversity
- The unique sequence of amino acids in each protein determines its specific function in the body.
- Proteins with different sequences can have vastly different functions, ranging from enzymes to structural components.
Therefore, the extensive diversity of protein molecules is primarily attributed to the sequence of amino acids, which governs the structure and function of each protein.
