Vitamin c deficiency may lead to scurvy, a disease characterized by skin lesions and blood vessel hemorrhages due to weakened connective tissue. vitamin c deficiency has this effect because the vitamin is a. a critical structural component of collagen. b. required for the enzymatic activity of prolyl hydroxylase. c. required for the enzymatic activity of cellulose synthase. d. required for the enzymatic activity of hydroxyprolyl hydroxylase.

(b). required for the enzymatic activity of prolyl hydroxylase.

Explanation:

Scurvy is a disorder, caused by deficiency of vitamin C in diet as vitamin C is not synthesized in body.

Vitamin C acts as a cofactor for enzymatic activity of lysyl hydroxylase and prolyl hydroxylase. These two enzymes are required for the stabilizing cross-linking between peptides of collagen protein.

As collagen is a primary structural protein, rewired for healthy skin, blood vessels, and muscles, vitamin C deficiency leads to scurvy.

Thus, the correct answer is option (b).
