Haem protein complexes that act as oxidising agents during plant respiration

Haem protein complexes that act as oxidising agents during plant respiration are known as

Options

(a) Chlorophyll
(b) Haemoglobin
(c) Myoglobin
(d) Cytochrome

Correct Answer:

Cytochrome

Explanation:

Cytochromes are small proteins (intrinsic membrane proteins) that contains a cofactor, haem which holds an iron atom. The iron carries electrons and cycles between +2 and +3 oxidation states. These form a part of electron transport chain in mitochondria and chloroplast and act as an electron transporter or electron acceptor in respiration and photosynthesis.
