4. Oxaloacetate uniformly labeled with "C (ie with equal amounts of "C in each of its carbon atoms) is condensed with unlabeled acetyl-CoA. After a single pass through the citric acid cycle back to oxaloacetate, what fraction of the original radioactivity will be found in the oxaloacetate? [10 points]

Assume a cell has just completed glycolysis and the resulting
pyruvate has a c-14 radio label on carbon -1. Highlight the carbon
on the attached pages as it passes through the PDH complex and the
TCA cycle until it is lost as CO2. If only a portion of the carbons
are lost stop highlighting when the CO2 first starts to come off.

Question 2a (1 pt): Alcohol dehydrogenase catalyzes the reversible reaction shown. In the space below, write the two half-reactions for the redox reaction. Then, determine the cell potential (AE) and standard Gibbs free energy change (AG) for the reaction. (Hint: Use Tables 13.7a/b in "Metabolism Overview") Acetaldehyde + NADH+H→ Ethanol + NAD Question 2b (1 pt): Under physiological conditions, the reaction actually proceeds in the direction that has a positive AG. What would be the minimum value of the reaction...
