WebMay 18, 2024 · Figure 8.6. 1: The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH 2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water. 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 ...
