- In the presence of oxygen, the mitochondrion in yeast is used for aerobic respiration,however, under anaerobic conditions,the yeast mitochondria have been found to have other function. Identify and briefly discuss four of these functionsarrow_forwardFill 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.
