Photosynthesis happens in two main stages, called the light-dependent stage and the light-independent stage. The light-independent stage is sometimes called the 'dark' stage.
The light-dependent stage can only happen in the light. During this stage light is absorbed and turned into chemical energy (ATP). Oxygen is also produced.
The light-independent stage can happen in the light or the dark ie it is independent of light! However, it needs substances made in the light-dependent stage so it cannot happen completely by itself.
In the light-independent stage the energy trapped as ATP in the light-dependent stage is used to change carbon dioxide into sugar (glucose).
The Calvin cycle converts carbon dioxide to carbohydrate.
CO2 --------> (CH2O)
This process requires an energy source and a hydrogen source, as well as carbon dioxide.
The energy source is ATP. The hydrogen source is NADPH. Both of these substances are produced by the light-dependent reactions.

Where does the dark reaction of the photosynthesis occur in?
It is not dark photosynthesis.It is dark reaction.It takes place in stroma.
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 happens during dark reaction phase and light reaction phase in photosynthesis?
during the dark phase assembly of gluscose takes place during the light phase molecular martial arts takes place
Does the dark reaction in photosynthesis split water?
yes :)
Can photosynthesis happen during nighttime?
yes,there are two reactions the light dependent and the light independent.pen the light independent is the reaction where the photosynthesis happen nighttime.
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 are the two reaction phases in photosynthesis?
light reaction and dark reaction
Is photosynthesis the chemical reaction that happens in a cell?
Yes, photosynthesis is a reaction typical for plants.
Where does the dark reaction of the photosynthesis occur in?
It is not dark photosynthesis.It is dark reaction.It takes place in stroma.
What is the dark reaction of photosynthesis also nown as?
The light independent reaction.
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 is the concept of the dark reaction as it relates to photosynthesis?
The dark reaction as it pertains to photosynthesis occurs when the plant, in the absence of sunlight, continue to supply energy. The dark side of photosynthesis relies upon the stored starches to fuel the energy cycles.
What happens during dark reaction phase and light reaction phase in photosynthesis?
during the dark phase assembly of gluscose takes place during the light phase molecular martial arts takes place
Can the dark reaction in photosynthesis occur after sunset?
no not Hitler
What are the comparison of light and dark reaction of photosynthesis?
i dont no the answer
Does the dark reaction in photosynthesis split water?
yes :)
What are the parts of photosynthesis?
There are two major steps.They are light reaction and dark reaction.
