High-Yield Explanation
Complex IV: Cyt-c Oxidase The system functions: * As proton pump * Catalyses transfer of electrons to molecular O2 to form H2O. This is the terminal component of ETC. It catalyzes the transfer of electrons from Cyt-c to molecular O2 Cyt-a, Cu++ ions and Cyt-a3.Ref: MN Chatterjea Textbook of Medical Biochemistry, 8th edition, page no: 142
