What is the purpose of the Z scheme in the photosynthesis process?
To transfer electrons from the reaction center of PS II to NADP⁺
To excite electrons in PS I
To absorb red light of 700 nm wavelength
To reduce NADP⁺ to NADPH + H⁺
Solution
The Z scheme refers to the transfer of electrons, starting from photosystem 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⁺ reducing it to NADPH + H⁺.
