Patients with pyruvate dehydrogenase deficiency show high levels of lactic acid in the blood. However, in some cases, treatment with dichloroacetate (DCA), which inhibits the kinase associated with the pyruvate dehydrogenase complex, lowers lactic acid levels. How does DCA act to stimulate pyruvate dehydrogenase activity? DCA activates pyruvate dehydrogenase kinase. DCA increases phosphorylation levels of pyruvate dehydrogenase. DCA inhibits pyruvate dehydrogenase kinase. ODCA activates pyruvate dehydrogenase phosphatase. What does this suggest about pyruvate dehydrogenase activity in patients who respond to DCA? The pyruvate dehydrogenase complex is active only when phosphorylated by the kinase. The pyruvate dehydrogenase complex is active only in the presence of the kinase. The pyruvate dehydrogenase complex is completely inactive. The pyruvate dehydrogenase complex displays some residual activity.
