Question

Inner mitochondrial membrane contains groups of electron and proton transporting enzymes. In each group, the enzymes are arranged in a series called electron transport chain. It is a series of coenzymes and cytochromes that take part in the passage of electrons from a chemical to its ultimate acceptor. At each step the electron carriers include flavins, iron sulphur complex, quinones and cytochromes. The table given below shows different complexes with their prosthetic groups.\ Which complex contains two copper centres?\
