Question

Describe how ATP is produced in the light reactions.

Answer 1

Answer:

Explanation:

Two reactions take place that produce raw materials for the dark stage:  

1. Light energy splits the water molecules into hydrogen and oxygen
2. This process is called photolysis  

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 Adenosine Triphosphate (ATP)

Hope this helps.
