Botany - Photosynthesis in Higher Plants Question with Solution | TestHub

The general word formula for photosynthesis is -

$6{\mathrm{C}\mathrm{O}}_2+12{\mathrm{H}}_2\mathrm{O}\to \mathrm{ }{\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6+6{\mathrm{H}}_2\mathrm{O}+6{\mathrm{O}}_2$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${\mathrm{N}\mathrm{A}\mathrm{D}\mathrm{P}\mathrm{H}}_2$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.
