Question

Photooxidation of water results in the formation of

• A. H${}^{+}$, O${}_2$, ATP
• B. H${}^{+}$, O${}_2$, e${}^{-}$, ATP
• C. H${}^{+}$, O${}_2$, e${}^{-}$
• D. None of the above

Answer 1

The correct option is C H${}^{+}$, O${}_2$, e${}^{-}$

A) One electron is released per molecule of water that is split. ATP is not released.
B) ATP is not released as a byproduct of the splitting of water.

C) Photooxidation or photolysis of water occurs in the LHC of PS II where water is split by light to liberate $H^{+},O_2,e^{-}$.

D) Water splits to liberate $H^{+},O_2,e^{-}$
So the correct answer is '$H^{+},O_2,e^{-}$'.
