Enzyme-substrate specificity is a result of which property of enzymes?

Explanation

The specificity of the substrate of the protein structure is determined by the tertiary structure. The proteins have a very specific shape due to their tertiary structure which plays important role in the lock and key mechanism of the enzymes. Hence option c is correct.The primary structure deals with the sequential arrangements of amino acids in a protein chain. The primary structure determines the three-dimensional shape of the proteins. Hence option A is incorrect.The quaternary structure of proteins deals with the association of several protein chains. This is closely related to the functions of proteins. Hence option D is incorrect.The secondary structures of protein help us to predict the tertiary structure of proteins because determining structure based on arrangements of amino acids is insufficient. The protein structure and folding are estimated by secondary structure. It cannot determine the specificity of the substrate hence option B is incorrect.
