| Abstract: | Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Petra Hellwig reports administrative support was provided by University of Strasbourg. If there are other authors, they declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper. Terminal oxidases are critical for aerobic respiratory chains of prokaryotes and eukaryotes, responsible for the final step in the electron transport chain. These enzymes catalyze the transfer of electrons from reduced electron carriers (such as cytochrome c or quinols) to the terminal electron acceptor, molecular oxygen (O₂), thereby reducing it to water. They play a pivotal role in aerobic respiration and energy metabolism, adapting to diverse environmental and physiological needs across different organisms. This review summarizes the electrochemical properties of terminal oxidases from different organisms and reveals their high degree of adaptivity with redox potentials spanning more than 500 mV. The electrocatalytic response in direct electrochemical approaches is described giving insight into the rich and complex electron and proton transfer catalysed by these essential enzymes.
