How are light reactions and dark reactions different and similar?
Wiki User
∙ 12y ago
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 :)

∙ 13y agolight phase (also known as hill reaction), takes place using sun's energy (it uses photons to break the water molecules to release O2), also the reducing factors (NADPH) are formed in the light reaction. The reducing factors are used in the Dark reaction (biosynthetic phase) to reduce the CO2 molecule into glucose.
i just copied it from somewhere..if you aren't satisfied. then go and find the answer somewhere else..

∙ 14y agothe difference between light reaction and dark reaction is light reaction needs a light to produce food while the dark reaction dont need a light to produce food.

∙ 11y agolight reaction involves day light while dark reaction not neec light to complete
Wiki User
∙ 11y agoA light reaction is not as acidic and harsh whereas the dark reaction is heavy, acidic and more risky.

How do the light reactions and dark reactions work together?
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.
In what organelle do light reactions occur in plants?
Both light and dark reactions occur in the chloroplasts of cells. More specifically light reactions take places in the thylakoid, dark in the stroma.
Differentiate light reaction dark?
light reactions in plants takes place in the sun.reactions which occur after the light reactions are 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.

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."
