Arrange the sequence of reactions that occur in the conversion of pyruvate to acetyl-CoA in the correct order: The anion of the hydroxyethyl group attacks one sulfur of the disulfide in lipoic acid, and the resulting intermediate is oxidized to an acetyl thioester. FAD is reduced to FADH2, while the two thiols of reduced lipoic acid are oxidized back to a disulfide. FADH2 is oxidized by NAD producing NADH. Nucleophilic addition of thiamine pyrophosphate to pyruvate to yield hydroxyethyl-TPP and CO2. The acyl thioester derived from lipoic acid

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
