In mitochondria, enzyme cytochrome oxidase is present in
Open in App
Solution
The correct option is B Inner membrane
The enzyme
cytochrome c oxidase, or complex IV, is a large transmembrane protein complex found in inner
membrane of mitochondria. It receives an
electron from each of four cytochrome c molecules and transfers them to one oxygen molecule,
converting molecular oxygen to two molecules of water. In the process, it binds
four protons from the inner aqueous phase to make water and in addition
translocates four protons across the membrane, helping to establish a
transmembrane difference of proton electrochemical potential that
the ATP synthase then uses to synthesize ATP
So, the correct answer is 'Inner membrane'
