The electron transport chain in plants consists of an electron carrier called?
Correct answer: E. Both A and B
- A. Pq
- B. Pc
- C. Pt
- D. Po
- E. Both A and B
Explanation
Pq (plastoquinone) is the electron carrier in the electron transport chain of plants.Pc (plastocyanin) is another electron carrier protein, but it is not involved in the electron transport chain between PSII and PSI.The associated electron transport chain is NADH → Complex I → Q → Complex III → cytochrome c → Complex IV → O2, where Complexes I, III, and IV are proton pumps, while Q and cytochrome c are mobile electron carriers.
