T/F? In the citric acid cycle, ATP is produced by a substrate-level phosphorylation. T/F? Lipoamide is covalently linked to E2 of pyruvate dehydrogenase through an amide bond to the side chain of a Lys residue.
T/F? Lipoamide takes the acetyl group from TPP.
T/F? Fructose 2,6-bisphosphate activates glycolysis and inhibits gluconeogenesis via conversion of fructose 1,6-bisphosphate.
T/F? Carbons from glucose enter the citric acid cycle in the form of acetyl CoA.
T/F? The brain uses ketones instead of glucose for ATP production during long-term fasting.
T/F? Reduced dihydrolipoamide is oxidized by transferring electrons and protons to NAD+.
T/F? The aconitase reaction isomerizes Citrate to Isocitrate through an enediolate intermediate.
T/F? Oxaloacetate is carboxylated and then phosphorylated to produce phosphoenolpyruvate.
T/F? Gluconeogenesis is not the exact reversal of all steps in glycolysis.
T/F? The first step of gluconeogenesis takes place in mitochondrial compartment.
T/F? The thiol group of CoA attacks amide bond of acetyllipoamide to create the thioester bond of acetyl-CoA.
