Answer:
Explanation:
Two reactions take place that produce raw materials for the dark stage:
- Light energy splits the water molecules into <em>hydrogen</em> and <em>oxygen</em>
- This process is called <u>photolysis </u>
The hydrogen is taken up by a hydrogen acceptor called Nicotinamide adenine dinucleotide phosphate (NADP) while oxygen is released as a by-product .
2 H₂O(l) --------->light energy -------> 4 H + O₂ (photolysis
)
Light energy strikes the chlorophyll molecules and sets in motion a series of reactions resulting in the production of a high energy molecule called <em>Adenosine Triphosphate</em> (ATP)
Hope this helps.
