1.	What is Photophosphorylation? Given the types of Photophosphorylation.
Answer» Photophosphorylation : The process of formation of high-energy chemicals (ATP and NADPH). Cyclic photophosphorylation : Two photosystems work in series − First PSII and then PSI. These two photosystems are connected through an electron transport chain (Z. Scheme). Both ATP and NADPH + H⁺ are synthesised by this process. PSI and PSII are found in lamellae of grana, hence this process is carried here. Non-cyclic photophosphorylation : Only PSI works, the electron circulates within the photosystem. It happens in the stroma lamellae (possible location) because in this region PSII and NADP rectase enzyme are absent. Hence only ATP molecules are synthesised.
