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
What else can I help you with?
What is the product of the dark reaction in photosynthesis?
The product of the dark reaction in photosynthesis is glucose.
Why is a dark reaction called a cycle?
RuBP made during the dark reaction is used to start the reaction again. novanet.
What is another name for the dark reactions of photosynthesis?
Calvin cycle or light independent reaction
What are the requirement the dark reaction?
adaw
How are light reactions and dark reactions different and similar?
Differences: >light reactions occur in the thykaloid membranes, but dark occur in stroma >light reactions are light dependent, or they need light to take place, whereas dark reactions don't > dark reactions use the products of the light reactions >light reactions are the first step of photosynthesis and dark reactions are the second step Similarities: >both in photosynthesis Thats really the only similarity!!! hope this helps :)
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 light reaction produces ATP and NADPH, which are needed to fuel the dark reaction. The dark reaction (Calvin Cycle) uses the ATP and NADPH produced in the light reaction to fuel the conversion of carbon dioxide into glucose. In essence, the light reaction provides the energy source that drives the dark reaction.
What is the product of the dark reaction in photosynthesis?
The product of the dark reaction in photosynthesis is glucose.
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?
What is the product of the dark reactions?
DARK REACTION - In stroma -synthesis - C12
Why is the dark reaction a cycle?
RuBP made during the dark reaction is used to start the reaction again. novanet.
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
What are the two reaction phases in photosynthesis?
light reaction and dark reaction
What type of reaction is the Calvin cycle?
Dark reaction
Why is it light reaction presequisite to the dark reaction?
without ATP and (NADPH +H+) WE cannot run the dark reaction.and this molecules are produced from the light reaction.
