WebOX+ normally means the bacterium contains cytochrome c oxidase (also known as Complex IV) and can therefore use oxygen for energy production by converting O 2 to H 2 O 2 or H 2 O with an electron transfer chain. The Pseudomonadaceae are typically OX+. The Gram-negative diplococci Neisseria and Moraxella are oxidase-positive. WebCytochrome c transfers electrons from cytochrome c 1, the terminal component of complex III, to the four redox centers of the cytochrome oxidase complex. The transfer of four electrons from each of the four redox centers of the cytochrome oxidase complex to an oxygen molecule occurs in a concerted manner to yield two molecules of water:
