Question 23 2 pts As it turns out, arsenic is a competitive inhibitor of pyruvate dehydrogenase. Suppose you add arsenic to human muscle tissue in a laboratory. What results would you expect to observe? I. Decreased ability of the tissue to relax after contraction II. Increased concentration of ADP in the mitochondrial matrix III. Increased concentration of lactic acid in the cytosol IV. Increased concentration of NADH and FADH2 in the mitochondrial matrix I, II, and IV II, III, IV I and II I and IV I, II, and III
