QUESTION 44 Gluconeogenesis can be described as "glycolysis backwards" but some enzymes are replaced by different enzymes in gluconeogenesis Which of the following enzyme(s) is / are needed to replace pyruvate kinase? OA phosphogycerate mutase OR phosphoenolpyruvate carboxykinase Oc pyruvate carboxylase OD pyruvate dehydrogenase OE both B and C are needed to replace pyruvate kinase QUESTION 45 Oxaloacetate appears in multiple pathways in metabolism. Which of the following statements describing its role is incorrect? OA it will be converted to malate to be removed from the mitochondria to be used in gluconeogenesis in the faste state OB. it will be replenished by the action of pyruvate carboxylase in the fed state Ocit will condense to form citrate with acetyl CoA in the tricarboxylic acid cycle in the fed state O D.it will condense to form citrate with acetyl CoA in the tricarboxylic acid cycle in the fasted state OE none of the above statements (A, B, C, or D) are incorrect
