Question

In the above schematic diagram which is plastocyanin?

• A. a
• B. b
• C. c
• D. d.

Answer 1

The correct option is D d.

In the electron transport process, the excited electron from PS II is accepted by primary acceptor quinone, which sends them to an electron transport system consisting of plastoquinone, cytochrome complex and plastocyanin.

The excited electron absorbed by PS I reaction centre, then transfer to the ferredoxin(Fe), then the reduced Ferredoxin donates the electron to NADP${}^{+}$.

So, a- excited PS II, b- Quinone, c- plastoquinine, d- plastocyanin.

Hence, the correct answer is 'd'.
