Solution
The question is asking how many of the given statements about the tertiary structure of proteins are incorrect. Let's go through them one by one:
(i) Gives 3-D view of protein - This statement is correct. The tertiary structure of a protein refers to its three-dimensional shape.
(ii) Peptide bonds are absent - This statement is incorrect. Peptide bonds are present in all levels of protein structure, including the tertiary structure. They are the bonds that hold amino acids together in a protein.
(iii) Most of proteins in protoplasm exhibit tertiary structure - This statement is correct. Most proteins in a cell do have a tertiary structure.
(iv) Gives Globular appearance - This statement is correct. Many proteins with a tertiary structure have a globular, or roughly spherical, appearance.
(v) Most stable structure of protein - This statement is incorrect. The most stable structure of a protein is its primary structure, which is the sequence of amino acids in the protein.
So, out of the five statements, two (ii and v) are incorrect.
