B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C) If the assertion is true but the reason is false
D) If both the assertion and reason are false
E) If the assertion is false but reason is true
Correct Answer: E
Solution :
The overall equation of photosynthesis is \[C{{O}_{2}}+2{{H}_{2}}O+n(h\nu )\to (C{{H}_{2}}O)+{{H}_{2}}O+{{O}_{2}}.\] The standard free-energy change for the synthesis of hexose from \[C{{O}_{2}}\]and \[{{H}_{2}}O\]is \[\Delta G{}^\circ =+686\ kcal.\] As six molecules of \[C{{O}_{2}}\]is involved to form one molecule of hexose, the energy input per \[C{{O}_{2}}\]molecule will be 114 kcal.
