Question

Quizplus · Accepted Answer

Statement 1 is false because the primary function of vitamin D is to regulate calcium and phosphate in the body, not to act as an antioxidant. Statement 2 is true; holoenzymes are indeed conjugated enzymes, consisting of an apoenzyme and a cofactor. Statement 3 is false because an increase in temperature only increases enzyme activity up to a point, beyond which the enzyme denatures and its activity decreases.
