1. Oxaloacetate can be converted into several different metabolic compounds. Briefly discuss each one, and include whether that is part of a catabolic or anabolic pathway. 2. There are several allosteric regulators of pyruvate carboxylase. For each one, explain the following: o Is this molecule an allosteric activator or allosteric inhibitor? o Why does it make sense that it would regulate the enzyme in that way? o Does this inhibitor/activator stabilize the R state or T state of the enzyme? Acetyl CoA Aspartate 3. Draw a...

Compare the ATP yield of three glucose molecules that enter glycolysis and are converted to pyruvate with that of three glucose molecules that proceed through the pentose phosphate pathway such that their carbon skeletons (as two F6P and one GAP) reenter glycolysis and are metabolized to pyruvate. Indicate the steps where ATP was used or produced and the overall ATP totals.

In gluconeogenesis, pyruvate is converted to PEP in two reactions. These reactions include an initial carboxylation followed by a decarboxylation in the second reaction. Based on these two reactions, you would assume that if radio-labeled 14CO2 was present in the reactions, it would not be incorporated into PEP. However, when 14CO2 is present with rat liver cells 14C slowly begins to appear in PEP and eventually on carbons 3 and 4 of glucose. Diagram a series of reactions that would...

Cytosolic pyruvate is the end product of glycolysis. Its fate depends on the metabolic status of the cell. If there is plenty of oxygen, the aerobic pathway dominates. If oxygen is insufficient, the anaerobic pathway dominates. Associate each of the following characteristics with either the aerobic or anaerobic fate of pyruvate. Catalyzed by lactate dehydrogenase Catalyzed by pyruvate dehydrogenase complex Oxidizes NADH Oxidizes pyruvate Produces acetyl CoA Produces lactate Recycles NADH to NAD+ Redirects glucose oxidation to the mitochondrion Reduces...
