Question : Assertion: The whole scheme of transfer of electrons, starting from the PS II uphill to the acceptor, down the electron transport chain to PS I, excitation of electrons, transfer to another acceptor, and finally downhill to NADP^(+) causing it to be reduced to NADPH^(+) H^(+)~ is called the Z scheme or cyclic photophosphorylation. Reason: Both ATP and NADH + H^(+) are synthesised by this kind of electron flow.

Question : Assertion: The whole scheme of transfer of electrons, starting from the PS II uphill to the acceptor, down the electron transport chain to PS I, excitation of electrons, transfer to another acceptor, and finally downhill to NADP^(+) causing it to be reduced to NADPH^(+) H^(+)~ is called the Z scheme or cyclic photophosphorylation. Reason: Both ATP and NADH + H^(+) are synthesised by this kind of electron flow.
Answer» If both assertion and reason are true and the reason 1s the correct explanation of the assertion. If both assertion and reason are true but reason is not the correct explanation of the assertion. If assertion is true but reason is false. If both assertion and reason are false. Solution :The whole scheme of transfer of electrons, starting from the PS II uphill to the acceptor, down the electron transport chain to PS I, excitation of electrons, transfer to another acceptor, and finally downhill to NADP causing it to be reduced to `NADPH+H^(+)` is called the Z scheme or non-cyclic photophosphorylation. Both ATP and NADPH are SYNTHESISED by this kind of electron FLOW.
