Solution

The correct option is D Cellular respiration
Cytochromes are heme proteins containing heme groups and are electron carriers. It catalyze oxidation-reduction reactions during cellular respiration. For photosynthesis, the cytochrome $b_{6}$ f complex transfers electrons between the two reaction complexes from Photosystem II to Photosystem I, whereby introducing protons into the thylakoid space to generate an electrochemical gradient that stores energy for ATP synthesis. Thus, option D is correct.
