What are the entry points for the reduced forms of NAD+ and FAD in the electron transport chain? C. what is the final electron acceptor in the electron transport chain?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.
