Answer:
Explanation:
Two reactions take place that produce raw materials for the dark stage:
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.
The process of how ATP is produced in the light reactions is explained below.
The energy gotten by the hydrogen ion stream gives room for ATP synthase to attach a third phosphate to ADP. Through this attachment, a molecule of ATP is formed in a process called photophosphorylation.
Light absorbed during this reaction and the energy, is used to drive electrons from water to generate NADPH and to drive protons across a membrane.
These protons that are driven often return through ATP synthase to make ATP.
Cellular respiration also produce ATP and water, that is used in different chemical reactions in the plant cell.
