WebApr 12, 2024 · A) NADH-O 2 oxidoreductase and B) succinate-O 2 oxidoreductase activity are plotted against increasing rotenone and malonate concentrations (logarithmic scale), respectively. Data plotted to determine the i 0.5 value. C) Effect of rotenone and malonate at fixed concentration on NADH or succinate and NADH plus succinate oxidation. WebATP, ADP, and NADH are examples of molecules that regulate cellular respiration enzymes. ATP, for instance, is a "stop" signal: high levels mean that the cell has enough ATP and does not need to make more through cellular respiration. This is a case of feedback inhibition, in which a product "feeds back" to shut down its pathway.
