Question

Which of the following is incorrect regarding the process X?


(a) It uses oxygen to liberate energy.
(b) Oxidation of glucose occurs.
(c) It releases oxygen and water.
(d) It consumes carbon dioxide and water.

• A. (c) and (d)
• B. (a) and (b)
• C. (a) and (c)
• D. (b) and (c)

Answer 1

The correct option is B (a) and (b)

‘X’ here refers to the process of photosynthesis in which following reaction takes place:
$6C{O}_2+12H_{2}O\stackrel{light}{\to }{C}_6{H}_{12}{O}_6+6O_2+6H_{2}O$
Here, Carbon dioxide is getting reduced, while water is getting oxidised and the formation of glucose, water and oxygen takes place. Oxygen produced is liberated in the atmosphere.
