A) Large amount of\[C{{O}_{2}}\], no water and no energy.
B) 132 gms of\[C{{O}_{2}}\], 54 gms of water and 337 kcals of energy.
C) 264 gms of\[C{{O}_{2}}\], 108 gms of water and 674 kcals of energy.
D) 528 gms of\[C{{O}_{2}}\], 216 gms of water and 1348 kcals of energy.
Correct Answer: C
Solution :
[c] Reaction of respiration is \[{{C}_{6}}{{H}_{12}}{{O}_{6}}+6{{O}_{2}}\to 6C{{O}_{2}}+6{{H}_{2}}O+674kcal\] In this reaction considering molecular weight of each element, we get \[{{C}_{6}}{{H}_{12}}{{O}_{6}}=6\times 12+12\times 1+6\times 16=180gm\] \[{{O}_{2}}=3\times 32=192gm\] Now we consider products of this reaction i.e. \[\begin{align} & 6C{{O}_{2}}and6{{H}_{2}}O \\ & 6C{{O}_{2}}=6(12+32)=264gm \\ & 6{{H}_{2}}O=6(2+16)=108gm \\ \end{align}\]
