Light Reaction (involves the sun)
The roots suck up water from the ground, into the chloroplasts. In there, the water is sun-heated and gets split into hydrogen, oxygen and ATP. The oxygen then gets released for us to breath and the hydrogen is put to a different part of the leaf.
Dark Reaction (doesn't involve the sun)
After the hydrogen gets to the other part of the leaf, the CO2 (carbon dioxide), that we breath out, mixes with the hydrogen and gets fused using ATP, making sugar/starch.

What is light reaction and dark reaction?
Photosynthesis can be divided into two part: light reaction is the first stage of photosynthesis, occurring only in the presence of light, during which energy captured from light drives the production of ATP. dark reaction is the second stage of photosynthesis, not requiring light to occur, and during which energy released from ATP drives the production of organic molecules from carbon dioxide.
What type of chemical reaction is photosynthesis?
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
Why bromometric titration done in dark conditions?
Bromometric titration is done in dark conditions because the reaction between bromine and the analyte is photo-sensitive. Light can cause the bromine to decompose and give inaccurate results. Performing the titration in the dark ensures the accuracy and reliability of the titration results.
Why iodine kept in dark during titration?
iodine solution should be kept in dark because it is highly photosensetive.light accelerates a side reaction in which iodide ions are converted to iodine..
What are light reactions and dark reactions?
light reaction is photolysis which mean using light or photon to lysis or break the water molecules into oxygen and hydrogen ion, H+. Dark reaction or the calvin cycle uses hydrogen ion to convert carbon dioxide into glucose
What is the difference between light and dark called?
color
What is the difference between light and dark photosynthesise?
The light is used for photolysis of water and converting the radiant energy into chemical energy. These energy rich compounds during dark reaction assimilate carbon from carbon dioxide to form carbohydrates.
Biology 10th class guide of chapter Life Processes?
1.what is the difference between light and dark reaction? 2.explain dark and light reaction?
What is the difference between light and dark kidney beans?
i thinks its an 'aidan bean '
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.
Difference between working drawing and 3d model and sketch?
the difference is stechn is when its light drawn is when its dark!!
How are light reactions and dark reactions different and similar?
Light reactions occur in the thylakoid membrane of chloroplasts and require light energy to convert it into chemical energy in the form of ATP and NADPH. Dark reactions (Calvin cycle) occur in the stroma and use ATP and NADPH to fix carbon dioxide into sugars. Both processes are part of photosynthesis and work together to convert light energy into chemical energy.
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
