C.
cristae of mitochondria
Cytochromes are present on the cristate, i.e. inner foldings of mitochondria. Cytochromes are iron (heme) containing proteins primarily responsible for transfer of electrons in ETC from ubiquinone to complex-V for generation of ATP(energy molecules) and terminal acceptor O2 in electron transport chain.
They are also called respiratory pigments, which are capable of performing both the oxidation and reduction reactions.
The energy -releasing process in which the substrate is oxidised without an external electron acceptor called
fermentation
photorespiration
aerobic respiration
