47. No exchange. Mice that completely lack ATP-ADP translocase (ANT- /ANT - ) can be made by using the knockout technique. Remarkably, these mice are viable but have the following pathological conditions: (1) high serum levels of lactate, alanine, and succinate; (2) little electron transport; and (3) a six- to eightfold increase in the level of mitochondrial H2O2 compared with that in normal mice. Provide a possible biochemical explanation for each of these conditions.
