Question

During photochemical reaction of photosynthesis:

• A. Liberation of $O_2$ takes place
• B. Formation of ATP and NADPH${}_2$ take place
• C. Liberation of $O_2$, formation of ATP, and $NADPH$ take place
• D. Assimilation of $C{O}_2$ takes place

Answer 1

The correct option is C Liberation of $O_2$, formation of ATP, and $NADPH$ take place

Light reactions or the ‘photochemical’ phase include light absorption, water splitting, oxygen release. The splitting of water is associated with the PS II - water is split into H+, [O] and electrons. This creates oxygen, one of the net products of photosynthesis and the formation of high-energy chemical intermediates, ATP and NADPH. The light reactions capture energy from sunlight, which they change to chemical energy that is stored in molecules of NADPH and ATP.
