Malate dehydrogenase is the enzyme that contributes to the final product, which is recycled in this reaction to yield citrate after coupling with another two-carbon compound.  
In the second and third steps of this biochemical reaction, the enzyme aconitase promotes the dehydration of the first product, yielding cis-aconitate, and then isocitrate.  Malate dehydrogenase is the enzyme that contributes to the final product, which is recycled in this reaction to yield citrate after coupling with another two-carbon compound.  Involving the conversion of NAD+ to NADH and FAD to FADH2, this reaction produces oxaloacetate, which binds to said two-carbon compound.  FTP, identify this cycle of cellular respiration that starts by bonding acetyl CoA to pyruvate.
