Question

Assume you have a solution containing the pyruvate dehydrogenase complex and all the enzymes of the TCA cycle but none of the metabolic intermediates. when you supplement the solution with five umoles each of pyruvate, oxaloacetate, coenzyme A, NAD, FAD, GDP, and Pi you find that five umoles of C02 are evolved and then the reaction stops. when you add alcohol dehydrogenase and its substrate acetaldehyde additional C02 is produced 1. How do you explain this result? 2. How many umoles of Acetaldehyde are required to allow complete oxidation of the pyruvate to 15 umoles of C02

Explanation / Answer

answer 1:- because alcohol is converted to aldehyde and on oxidation it releases co2

answer 2:-
