Peroxidase is an enzyme found in many organisms, from plant to humans. The function of peroxidase is to break down hydrogen peroxide, which is a toxin produced as a byproduct when oxygen is produced during respiration. Lactoperoxidase is found in human tissues, glands, and secretions, such as milk, tears, and saliva. It plays an important role in defense against pathogenic microorganisms in the intestinal tract of newborn infants and a protective role in sterility of secretions for the respiratory tract. For lactoperoxidase to function properly, thiocyanate is needed. A: Identify two examples of environmental factors that may impact lactoperoxidase activity. Describe how each of the environmental factors would affect the reaction rate of the enzyme.

B: Predict the effects of defects in the thiocyanate transport channels. Provide reasoning to justify your prediction.
