Q. Read the given statements and select the correct option.
Statement 1 : During photophosphorylation (of photosynthesis), light energy is utilised for the production of proton gradient during $ATP$ synthesis.
Statement 2 : In respiration, energy of oxidationreduction is utilised for the phosphorylation and thus the process is called oxidative phosphorylation.

Respiration in Plants

Solution:

Photophosphorylation occurs in the grana and requires the direct sunlight energy to make energy-carrier molecules that are used in the dark reaction. The light energy is trapped by chlorophyll to make $ATP$ and $NADPH$. Oxidative phosphorylation is the synthesis of energy rich $ATP$ molecules with the help of energy liberated during oxidation of reduced co-enzymes $(NADH$, $FADH_2)$ produced in respiration.
