Question

The reaction center for PS- I and PS- II are:

• A. $P_{700}$ and $P_{680}$ respectively
• B. $P_{600}$ and $P_{700}$ respectively
• C. $P_{580}$ and $P_{700}$ respectively
• D. $P_{700}$ and $P_{580}$ respectively

Answer 1

The correct option is A $P_{700}$ and $P_{680}$ respectively

Photosystem I has a reaction centre of P${}_7$${}_0$${}_0$ and photosystem II has reaction centre P${}_6$${}_8$${}_0$. Both are involved in non-cyclic photophosphorylation.
