Question

Classify the reaction that occurs at step 5 in the reaction schematic of the pyruvate dehydrogenase reaction below. 
A) isomerization 
B) addition 
C) oxidation reduction 
D) decarboxylation

Quizplus · Accepted Answer

Step 5 in the pyruvate dehydrogenase reaction involves the oxidation of a thioester bond, which is a form of oxidation-reduction reaction. The other choices (isomerization, addition, and decarboxylation) do not accurately describe the type of reaction occurring in this step.
