Question
Light dependent reaction results in the formation of __________.
- Oxygen
- ATP
- NADPH
- All the above
Hint:
All the above
The correct answer is: All the above
The three products of the light reaction of photosynthesis are ATP, NADPH and oxygen. In the non-cyclic photophosphorylation light first hits photosystem II where it excites electrons to a higher energy level. The electrons come from the photolysis of a water molecule producing Oxygen and H+ in the thylakoid space.
