[NAD+/NADH ratio in the mitochondria of the oocytes and ova of groundling, Misgurnus fossilis (L.)].
The ratio NAD+/NAD-H was detemined in mitochondria of the loach oocytes and eggs on the basis of concentrations of the glutamate dehydrogenase reaction intermediates. This ratio increases 6 times upon the oocyte maturation. The importance of this ratio in the metabolism of oocyte and embryo is discussed.
