Which molecule is oxidized in the initial lightdriven charge

Which molecule is oxidized in the initial light-driven charge separation reaction? PLEASE EXPLAIN

A.plastoquinone

B. the antenna complex

C. the special pair

D. chlorohpyll monomers

Solution

The reaction center is in the thylakoid membrane. It transfers light energy to a dimer of chlorophyll pigment molecules near periplasmic side of the membrane. This dimer is called special pair because of its fundamental roles in photosynthesis. This special pair is slightly different in PSI and PSII reaction center.

In PSII, it absorbs photons with a wavelength of 680 nm, and it is therefore called P680. In PSI, it absorbs photons at 700 nm, and it is called P700, Where \"P\" means pigment, and the number following it is the wavelength of light absorbed. The initial charge separation occurs in less than 10 picoseconds.

So, the correct answer is Option C.
