Question

Choose the correct answer from the alternatives given.
Which of the following statements is not true about photosystems?

• A. Photosystem-l passes electrons on to photosystem-II
• B. Each photosystem contains numerous pigment molecules that act as antennas to capture light
• C. Photosystem-l contains a reaction center molecule that absorbs light best around 700 nm, so it is called $P_{7}00$
• D. Electrons in the reaction center molecule are excited by absorbed photons of light and are passed along to an acceptor molecule

Answer 1

The correct option is A Photosystem-l passes electrons on to photosystem-II

Photosystem-II or P700 first accepts electrons and then passes it onto Photosystem-I. Each photosystem is serviced by the light-harvesting complex, which passes energy from sunlight to the reaction centre; it consists of multiple antenna proteins that contain a mixture of 300–400 chlorophyll a and b.

So, the correct option is, 'Photosystem-l passes electrons on to photosystem-II'.
