Q. During photosynthesis, the oxygen from $C O_{2}$ is incorporated into

NTA AbhyasNTA Abhyas 2020Photosynthesis in Higher Plants

Solution:

The general word formula for photosynthesis is -
$6C O_{2}+12H_{2}O \rightarrow \, C_{6}H_{12}O_{6}+6H_{2}O+6O_{2}$ in presence of light and chlorophyll. The whole photosynthesis process is divided into two broad parts -
Light reaction where the light energy is used to generate ATP and $N A D P H_{2}$ which is later used in the Dark reaction to reduce carbon dioxide into glucose (carbohydrate) molecule. The free oxygen released as a byproduct in the photosynthesis occurs by splitting water. The oxygen of the carbon dioxide is used in making the glucose molecule through the Calvin cycle.
