SOLVED: The pyruvate dehydrogenase (PDH) complex catalyzes the oxidativedecarboxylation of pyruvate to acetyl-CoA and CO2. Multiple copiesof pyruvate dehydrogenase (E1), dihydrolipoyl transacetylase (E2),and dihydrolipoyl dehydrogenase (E3) along with five cofactors formthe PDH complex. Biochemists have studied the PDH complex fordecades, in part due to its interesting use of substrate channelingduring catalysis. What is the benefit of substratechanneling? What is the molecular mechanism of subs

SOLVED: Arsenite poisoning directly affects the function of this cofactor in the pyruvate dehydrogenase complex:Select one:A. Thiamine diphosphate (TPP)B. LipoamideCo-enzymeD. NADE: FAD

SOLVED: '1.) ( 5 pts) Draw the mechanism of pyruvate dehydrogenase beginning with pyruvate lipoamide, NAD and TPP in the ylid form; draw the mechanism of the formation of Acetyl CoA Draw the structure of any relevant intermediates You may use B and B: for the general acid base groups. PUSH ARROWS! H;C'

SOLVED: (A) A cell is deficient in pyruvate dehydrogenase phosphatase. How would such a deficiency affect cellular metabolism?(B) A cell has a metabolic defect in the citric acid cycle that causes inhibition of pyruvate dehydrogenase kinase 2, and consequent activation of HIF-1, hypoxia-induced factor 1. Compare the metabolic effects of this situation to part (a) of this problem.
