Assume you have a solution containing the pyruvate dehydrogenase complex and all the enzymes of the citric acid cycle, but none of the metabolic intermediates. When you supplement this solution with 7 μmolμmol each of pyruvate, oxaloacetate, coenzyme A, NAD+NAD+, FADFAD, GDPGDP, and PiPi, you find that 7 μmolμmol of CO2CO2 are evolved and then the reaction stops. When you add alcohol dehydrogenase and its substrate acetaldehyde, additional CO2CO2 is produced. Part APart complete Part B How many μμmoles of acetaldehyde are required to allow complete oxidation of the pyruvate to 21 μmolμmol of CO2CO2?

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
