Oxygen is what is released.
Oxygen
Light allows photosynthesis to occur. Therefore more light=faster reaction.
Water is the molecule that is split during the light reaction of photosynthesis when releasing oxygen.
6CO2+6H2O+light energy-->C6H12O6+6O2 Chemical reaction of Photosynthesis
Oxygen is what is released.
Oxygen
An exothermic reaction is a reaction where heat or light energy is released. An example of this type of reaction is burning a candle.
why light reaction of photosynthesis is essential before the dark reaction can procced?
Usually, a "light dependent reaction" refers to photosynthesis, which produces oxygen to be released, and glucose for the plant to use for energy.
Oxygen is released as a by product of photosynthesis.
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.
light reaction and dark reaction
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.
Light allows photosynthesis to occur. Therefore more light=faster reaction.
# photosynthesis 2. Water is the source of hydrogenduring the light dependent reaction of photosynthesis. Water is split into hydrogen and oxygen. The oxygen is released into the atmosphere and the hydrogen is transferred to a carrier molecule called NADP, to produce NADPH. The NADPH is then used in the light independent reaction to reduce carbon dioxide to carbohydrate. See my answer to this question on WikiAnswers: What connects the light dependent reaction to the light independent reaction?
