How does malonate affect cellular respiration
WebMar 16, 2024 · It decreases cellular activity. Malonate is a competitive inhibitor of the enzyme succinate dehydrogenase: it binds to the active site of the enzyme without reacting, and so competes with succinate, the substrate of the enzyme. Thus chemical malonate decreases cellular respiration. Is diethyl malonate an acid? WebThis inhibition of mitochondrial electron transport increases cellular NADH which contributes to ROS formation and cell death by releasing iron from ferritin.

This does have a small local effect on the pH, but forming that NADH or FADH₂ used protons so it all balances out in the end. Comment Button navigates to ... Malonic acid is the classic example of a competitive inhibitor of the enzyme succinate dehydrogenase (complex II), in the respiratory electron transport chain. It binds to the active site of the enzyme without reacting, competing with the usual substrate succinate but lacking the −CH2CH2− group required for dehydrogenation. This observation was used to deduce the structure of the active site in succinate dehydrogenase. Inhibition of this enzyme decreases cell…
