(b) Identify the type of reaction or mechanism undergone in each case.
Fill in the bold using the table. Because the inner mitochondrial membrane is impermeable to L, when there is an excess of mitochondrial L, it converts to M using a TCA condensation reaction, M crosses to the cytosol using a designated transport system. In the cytosol, M reconverts to L and oxaloacetate. Oxaloacetate is subsequently converted to malate with simultaneous production of N, a prerequisite cofactor for the glycolysis pathway. This reaction is then followed by conversion of N to pyruvate which produces O, a prerequisite cofactor for the fatty acid synthesis pathway. L M N O A. ATP pyruvate malate NADPH B. ATP citrate ATP NAD+ C. acetyl CoA pyruvate NAD+ NADH D. acetyl CoA citrate NAD+ NADPH E. glucose pyruvate malate NADP+
