Which of the following statements with regard to photosynthesis is/are correct? I. In C3 plants, the primary CO_2 acceptor is RuBP. II. In the photosynthetic process, PS-II absorbs energy at or just below 680 nm. III. The chlorophyll-a that is present in the photosystem-I has absorption maxima at 680nm.

In the given statements (i-iv) i) The chlorophyll a is yellow green in colour and chlorophyll b is blue green in colour. ii) Both photosystems absorb more amount of red wavelength. iii) In moderate light, the chloroplasts arrange themselves with their flat surfaces perpendicular to the incident light while during strong illumination, they are parallel to the incident light. iv) The stroma of chloroplast is responsible for trapping the light energy and also for synthesis of ATP and NADPH.

Photolysis of water is important event of light reaction of photosynthesis.Read the following statements and choose the correct statement(s). Water splitting complex splits water into OH^- + H^+ . It is associated with photosystem-II. Water splitting Complex and photosystem-II both are present on the outer side of the thylakoid membrane.

Energy released during movement of electrons through the photosystems in photosynthesis is used to drive protons across the membrane against concentration gradient. As a result the protons accumulate in
