238070 In photosynthesis what occurs in PS-II

1 It takes longer wavelength of light and $\mathrm{e}^{-}$ from $\mathrm{H}_{2} \mathrm{O}$
2 It takes shorter wavelength of light and $\mathrm{e}^{-}$ from $\mathrm{H}_{2} \mathrm{O}$
3 It takes longer wavelength of light and $\mathrm{e}^{-}$ from NADP

Photosynthesis in higher plants

238073 Autoradiography technique was used to

1 trace the path of carbon in photosynthesis
2 establish that the oxygen evolved during photosynthesis is by photolysis of water molecule
3 study photorespiration in certain plants
4 find out the absorption maximum of chlorophyll pigments
Photosynthesis in higher plants

238046 Identify the incorrect statements among the following
I. When only PS I is functional, cyclic flow of electrons is not possible
II. The breakdown of the gradient provides enough to make the enzyme synthesis
III. The NADP reductase enzyme is located of the thylakoid membrane
IV. Proton gradient increases due to $\mathrm{PC}$ and Cyt f.
