Thus, in a cytochrome-rich system (homogenate) the characteristic stimu- latory effects may not be seen manometrically (O2 uptake) (see chart). Bodine et al. (1951) found a lowering of both endogenous and succinate-stimulated respira- tion (O2 uptake) by the addition of Malonate studies now in progress re- veal little or no succinic dehydrogenase involved in the endogenous respiration of homogenates. Thus it appears that reduction in the grasshopper embryo probably involves the sum of several physiologically active reductases.
