WebNational Center for Biotechnology Information 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.
