Q. In the given chart of photophosphorylation. What does ‘A’ represent?
A) PC
B) FRS
C) PQ
D) Cyt –$a_{3}$
Explanation
Plastoquinone transfer electron from photo system-II to photo system-I. Electrons released from $P_{700}$ or photo system-I moves through Fe-S, plastoquinone, cytochrome and plastocyanin and are recycled to $P_{700}$. In this process, only ATP is produced but no oxygen produced.
