in mitochondria cells of the wood of the enzyme will enable end succinic acid sodium dehydroacetate properties and succinic acid sodium H + to restore MTT dilemma of the soluble Blue purple formazan crystals and sedimentation in cells and dead cells, without this feature.

In the living cell line plastochondria succinic acid dehydrogenase can cause the substrate sodium succinate to escape H+, causes exogenetic MTT to return to original state awkward soluble royal purple crystallization thing formazan and precipitates in the cell, but the dead cell does not have this f

Succinate dehydrogenase in mitochondria of living cells can be substrate sodium succinate de H+, so that exogenous MTT reduction of embarrassing that the blue-violet crystals soluble formazan and precipitation in cells and dead cells without this feature.
