Question

Incorrect statement is:

• A. Water splitting complex is physically located on the inner side of the membrane of the thylakoid.
• B. The electrons needed to replace those removed from photosystem I are provided by PSII.
• C. The splitting of water is associated with PSII.
• D. Functioning of PSI is not necessary to synthesize $NADP{H}_2$.

Answer 1

The correct option is A Water splitting complex is physically located on the inner side of the membrane of the thylakoid.

• Water spilliting in the photosynthesis is done for providing electrons to the photosystem II complex which were transported to the photosystem I complex via a electron acceptor.
• Therefore the PS II is known as the water splitting complex where water molecule is split into 4 hydrogen ions and one molecule of oxygen and 4 electrons.
• The photosystem II is located on the inner membrane of the thylakoid.
• The electrons that are provided to PS I is provided by PS II which is used for the synthesis of NADPH+H from NADP.
• Therefore the correct answer is option D
