Consider the following statements regarding the denaturation of proteins: I. Denaturation can be caused by physical changes like temperature or chemical changes like pH. II. During this process, the uncoiling of helix and unfolding of globule takes place. III. The primary structure of the protein is altered during the coagulation of egg white on boiling. IV. Denaturation leads to the loss of biological activity of th

Step-by-step solution

Statement I is correct: Denaturation is caused by physical changes (such as heating) or chemical changes (such as a change in pH) that disrupt the native conformation of the protein. Statement II is correct: Denaturation involves the unfolding of globules and uncoiling of helices, which destroys the secondary and tertiary structures. Statement III is incorrect: The coagulation of egg white on boiling is an example of denaturation. During denaturation, the primary structure remains intact and is not altered. Stateme
