Botany - Photosynthesis in Higher Plants Question with Solution | TestHub

Photosystem I is located in the nonappressed part of grana thylakoids as well as stroma thylakoids. In this photosystem chlorophyll : carotenoid content is high. Its photocentre is ${\mathrm{P}}_{700}$. Pigment molecules of PS I absorb at or below 700 $\mathrm{nm}$ wavelenth of light. It receives electrons from photosystem II. Photosystem I is involved in both cyclic and non cyclic photophosphorylation. It is not connected with photolysis of water. Usually it hands over its electron to ${\mathrm{NADP}}^{+}$.
