Although some citric acid cycle enzymes operate primarily in the mitochondria, malate dehydrogenase operates in both the cytosol and the mitochondria. Match each function to cytosolic malate dehydrogenase or mitochondrial malate dehydrogenase. A. Cytosolic malate dehydrogenase

B. Mitochontrial malate dehydrogenase

1. transfers reducing equivalents from cytosolic NADH to a molecule that can tranverse the inner mitochondrial membrane

2. generates mitochontrial NADH from reducing equivalents that originate in the cytosol

3. reduces oxaloacetate to malate

4. oxidizes malate to oxaloacetate

5. reduces NAD+ to NADH

6. oxidezes NADH produced in glycosis to NAD+

7. catalyzes last reaction in citric acid cycle that regenrates oxaloacetate( ▲G = 29.7kJ/mol)
