It means that for a reaction (usually chemical) to take place, light is needed. An example of this can be seen in photosynthesis.
a substance that needs help from others substances to produce energy :p
goo
Carbon dioxide is the reaction pf photosynthesis. This takes a lot of energy.
what is waters roles in the light reaction of photosynthesis
6CO2+6H2O+light energy-->C6H12O6+6O2 Chemical reaction of Photosynthesis
photosynthesis
Reactants for photosynthesis are:WaterOxygenSugarsCarbon DioxideLight
Photosynthesis is a Endergonic/Endothermic reaction.
Photosynthesis is an endothermic reaction because it takes energy (from sunlight) from the environment to use in the photosynthesis reaction. Without the energy input, the photosynthesis reaction could not occur.
why light reaction of photosynthesis is essential before the dark reaction can procced?
Carbon dioxide is the reaction pf photosynthesis. This takes a lot of energy.
Yes, photosynthesis is a reaction typical for plants.
what is waters roles in the light reaction of photosynthesis
An exothermic reaction is a reaction where heat or light energy is released. An example of this type of reaction is burning a candle.
6CO2+6H2O+light energy-->C6H12O6+6O2 Chemical reaction of Photosynthesis
light reaction and dark reaction
photosynthesis
Cellular Respiration reverses photosynthesis.
