Question

Match the different levels of protein organization with their definition.

Answer 1

The protein undergoes multiple modifications in order to perform it's function and the structural significance of each type is given below.

Answer: Option B

Explanation:

The protein definitions are as follows:

Primary structure- Linear sequence of amino acids in the polypeptide chain.

Secondary structure- Highly regular local sub-structures such as α-helix and β-pleated sheet structures.

Tertiary structure- It is the Three-dimensional structure of a polypeptide.

Quatenery structure- Three-dimensional structure of a multi-subunit protein.

Answer 2

Answer: b.
Primary - sequence of amino acids with peptide bonds
Secondary - a-helix and b-pleated sheets with hydrogen bonds
Tertiary- 3D structure held together by R-group (most proteins only go to this level)
Quaternary- multiple sequences of amino acid chains
