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. Web1. Cyanide resistant respiration is believed to be responsible for the climacteric in fruits (i.e., remarkable increase in respiration during and just before ripening). The climacteric is induced by ethylene and the latter may act to implement the cyanide resistant respiration in ripening fruit, (production of H 2 O 2 and superoxide increases ...
