Question

Reaction centre of PS I is

• A. $P_{700}$
• B. $P_{680}$
• C. $Ch{l}_{715}$
• D. $Ch{l}_{685}$

Answer 1

The correct option is A $P_{700}$

Each photosystem is characterized by the wavelength of light at which it's reaction center absorbs maximum light i.e., 700 and 680 nanometers, respectively for PS I and PS II in chloroplasts. thus PS I is denoted by P${}_{700}$. Thus, the correct answer is 'P${}_{700}$'.
