Cytochromes contain copper ii
WebTwo cytochromes contain iron and one cytochrome contains copper. Here is an outline of the involvement of hydrogen in the ETC:-. At the beginning of the ETC, NADH2 is the reduced form of NAD. It has gained hydrogen ions. NAD is a hydrogen acceptor. Reduced NAD is a means of rephosphorylation of ADP > ATP. WebThe enzyme cytochrome c oxidase or Complex IV is a large transmembrane protein complex found in bacteria, archaea, and in eukaryotes in their mitochondria. It is the last enzyme in the respiratory electron transport chain of cells located in the membrane. It receives an electron from each of four cytochrome c molecules, and transfers them to ...
