<h2>Water;NADP is the correct option</h2>

Explanation:

Z scheme also known as non cyclic electron flow which starts with the absorption of light by photosystem II

Z scheme involves both photosystem(PS) I and photosystem(PS) II
Water becomes oxidized and oxygen gas is released/evolved as a result NADP+ gets reduced and produces NADPH
Oxidation of water and release of protons in lumen is done by PSII whereas reduction of NADP+ to NADPH is done by PSI
Oxidation of water molecule establish gradient of proton and this gradient drives synthesis of ATP

In the Z-scheme ____ is the initial electron donor and ____ is the final electron acceptor. A. Water; NADP B. NADPH; oxygen C. W
