Question

Which of the following is/are formed during Z-scheme of photophosphorylation?

• A. ATP
• B. $NADP{H}_2$
• C. $O_2$
• D. All of these

Answer 1

Answer: (D)

All of these

This 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 $NAD{P}^{+}$ causing it to be reduced to $NADPH+H^{+}$ is called as the Z scheme, due to its characteristic shape. This shape is formed when all the carriers are placed in a sequence on the redox potential scale.

So the correct option is 'All of these'.
