Basically, the dark reaction refers to the second stage of photosynthese- the Calvin Cycle, also called the dark reaction or light- independent reaction, because it does not require light energy. During this reaction, molecule of carbon dioxide is joined to RuBP (Ribulose Bisphosphate) by rubisco forming 3- PGA (phosphoglycerid acid). 3-PGA is then rearranged to G3P (three carbon molecule) while oxidizing ATP and NADPH. 2 G3P forms one glucose; one carbon molecule enters the cycle per turn. Since glucose is a 6 carbon sugar, the Calvin cycle have to run a total of 6 times to create oneglucose., using 18 ATP, 12NADPH, and 6 CO2

Which reaction makes ADP light or dark?
It is the light reaction. Then they moves to dark reaction
Do glucose get made in the dark reaction?
.yes.glucose is made in dark reaction.
Why must the light reaction occur before the dark reaction?
The bi product of the light reaction triggers the dark reaction.
Why is light reaction of photosynthesis essential for the dark reaction to proceed?
why light reaction of photosynthesis is essential before the dark reaction can procced?

Why light reaction first before dark reaction?
There must be a light reaction first before dark reaction. This is so that there is something to be compared.

Where does the oxygen produced in the dark reaction of photosynthesis come from?
It is obtained from air. Oxygen is not is not produced in dark reaction but in light reaction
