WebFeb 13, 2002 · In our simulations, the threshold for collapse of respiration also depends on the inward flux of protons across the mitochondrial inner membrane (Fig. 4 A): when proton uptake is faster, the threshold ρ res is shifted to a lower concentration range so that a greater fraction of carriers needs to be inhibited to affect respiration. WebMalonate, a classic inhibitor of respiratory electron transport chain, induces mitochondrial stress. Stress granules (SGs) are a kind of dynamic foci structure during stress. The study on the connection of mitochondrial stress and SG assembly is still limited. Here, we demonstrated that malonate tre … WebMalonate (malonic acid) has long been known to inhibit cellular respiration. Among the key observations made in the 1930s investigations into the nature of cellular respiration was that the addition of fumarate, malate, or oxaloacetate to cell preparations resulted in the accumulation of succinate in the presence of malonate. chevy cruze oil pan gasket
