Q. Which of the following is a simplified equation of photosynthesis?
A) $CO_{2} + 2H_{2}O\underset{Chlorophyll}{\overset{Light\ energy}{\rightarrow}}C_{5}H_{10}O_{4} + H_{2}O + O_{2} \uparrow$
B) $CO_{2} + 2H_{2}O\underset{Chlorophyll}{\overset{Light\ energy}{\rightarrow}}\left( {CH}_{2}O \right)_{n} + O_{2} \uparrow$
C) $CO_{2} + 2H_{2}O\underset{Chlorophyll}{\overset{Light\ energy}{\rightarrow}}C_{3}H_{6}O_{3} + {CO}_{2} + O_{2} \uparrow$
D) $CO_{2} + 2H_{2}O\underset{Chlorophyll}{\overset{Light\ energy}{\rightarrow}}\left( {CH}_{2}O \right)_{n} + H_{2}O + O_{2} \uparrow$
Explanation
Chemical equation for photosynthesis can be shown as $CO_{2} + 2H_{2}O\underset{Chlorophyll}{\overset{Light\ energy\ (hv)}{\rightarrow}}\left( CH_{2}O \right)_{n} + H_{2}O + O_{2} \uparrow$ or $6CO_{2} + 12H_{2}O\underset{Chlorophyll}{\overset{(hv)}{\rightarrow}}C_{6}H_{12}O_{6} + 6H_{2}O + 6O_{2} \uparrow$ Glucose
