Q. How many $H^{+}$ ions are formed from 12 water molecules during non-cyclic photophosphorylation?
A) 12
B) 24
C) 36
D) 48
Explanation
Each water molecule on photolysis yields one $H^{+}$ and $OH^{-}$ ion $H_{2}O \rightarrow 2H^{+} + \lbrack O\rbrack + 2e^{-}$ So, by $12H_{2}O$ molecule in photolysis 24 $H^{+}$ will product
