Light reactions require light to fix photons into Redox molecules. These are temporary, and to fix this energy for long term storage, the plants use the 'dark reactions' such as the Calvin cycle. It is sort of a misnomer, because they don't HAVE to occur in the dark, just that they don't require light.
What else can I help you with?
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.
Which reaction makes ADP light or dark?
It is the light reaction. Then they moves to 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.
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.
How does light and dark reactions correspond with parts of a leaf?
Dark reaction needs energy. this energy is supplied by light reaction
What are the two reaction phases in photosynthesis?
light reaction and dark reaction
Light Reaction and Dark Reaction?
Light Reaction is other wise known as a light in-dependent reaction.It need Photons(little packages of Light energy) from the sun that goes to the stoma and coverts it over the the next step....(Down Below)Dark Reaction is other wise known as a light dependent reaction. Inside the stoma into the thylakloids(they are little pancake shaped things)and they use ATP (made in light reaction) and NADPH to convert CO2 (carbon dioxide) into Glucose.-MPD-
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 the process of plant respiration?
the respiriration is such a oxidative reductive process ... and during plant it have two complex more process consist of seriese of steps DARK reaction and Light reaction.................... dark reaction need no light wheather in day time or night time...................... some how the light reaction are done in the prescence of light ..........during the light reaction the formation of the light reaction is just one ATP Which is responsible for the production of dark reaction .............
Why is the Dark Reaction sometimes called Light Independent Reaction?
Because the dark reactions are CO2 assimilation's and do not need light energy. They use the ATP and NADPH created from the light reactions to convert CO2 to carbohydrates, so this can happen in the "dark" as long as the light reactions already happened.
The dark reaction phase of photosynthesis occurs even without light as long as there suffcien supply of light reaction t lo?
The light reaction makes two substances needed by the dark reaction: ATP and NAPH. As long as these two substances are available the dark reaction can continue, even in the absence of light. However when they run out more light is needed to replace them.
