What product of light reactions are required for the dark reactions?
Wiki User
∙ 12y ago
The inputs of the Dark Reaction are NADPH, ATP, and CO2. The NADPH and ATP, which were produced in the Light Reactions, fix the carbon into a carbohydrate such as glucose. Enzymes are also needed for the Dark Reaction to take place. One such enzyme is Rubisco, which interacts with CO2 and RuBP in the first step of the Dark Reaction.

∙ 12y agoThe product is Hydrogen in the form of NADPH (Carrier molecule with hydrogen) which is taken to dark reactions to create glucose out of carbon and oxygen along with the hydrogen. Some oxygen and carbon are also brought from light reactions as a result of breaking down water and carbon dioxide. Primarily, it's the hydrogen that is needed in dark reactions that is a product of the light reactions.

∙ 14y agoA dark reaction, or Light independent reaction, uses ATP and NADPH (that was made dring the light dependent reaction) to transform CO2 (carbon dioxide) into Glucose.

Which reactions require oxygen as a raw material 1 light reactions only 2 dark reactions only 3 both light and dark reactions 4 niether light or dark reactions?
Neither, oxygen is a byproduct, not a reactant or "raw material."
What is released in light reactions of photosynthesis and which of these products does not participate in the dark reactions?
the light reaction is the first step to hydrolysis.No product is envolved except H2O + light in presence of chlorophyll.
Do the dark reactions occur in the thylakoids?
A dark reaction is done in the Calvin Cycle. Light is not needed at the time of the dark reaction but it also doesn't hinder the reaction if there is light at the time.So in short. Yes.
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.
What is the difference between the light dependent and the dark reactions of the Calvin cycle?
What is the difference between the light dependent and the dark reactions of the calvin cycle?
What photosynthetic products created by light reactions are required by dark reactions?
ATP and NADPH2
What is the end product of the dark reactions?
The end product of the dark reactions is glucose.
How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
How the light and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
How are light reactions and dark reactions similar and different?
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 :)
How do the light and dark Reaction work?
The light reactions provide energy carriers for the dark reactions.
How are the dark reactions that occur in plants dependent on the light-reactions?
The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.

What happens during each of the two stages of photosynthesis?
These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.

What process of photosynthesis can occur even when there is no light?
The Dark Reactions (a.k.a. The Calvin Cycle) can occur without the light. Sometimes they are also called the Light Independent Reactions for that very reason. Light is required during the light reactions because the energy from light (photon) is required to excite electrons. No such energy source is required for the Calvin Cycle because the energy has already been converted into a chemical form (ATP and NADPH) during the light reactions. The energy from ATP and NADPH is used to "drive" the Calvin Cycle (the accumulation of Carbon atoms from Carbon Dioxide). Carbon Dioxide and Rubulose Biphosphate (RuBp) are combined using the enzyme rubisco. The energy from ATP and NADPH is added (in several steps). The final molecule, gyceraldehye-3-phosphate (G3P) is produced. There is a fairly common misconception that glucose is the final product of the Calvin Cycle; but, it is actually G3P. Notice that none of these reactions (those of the Calvin Cycle) required light. And don't forget, plants don't need light for cellular respiration either.
