chemical reaction
which stages would be considered a light reaction?
The light reaction of photosynthesis takes place in the thylakoid membranes of the chloroplast in plant cells. This is where light energy is converted into chemical energy in the form of ATP and NADPH, which are essential for the later stages of photosynthesis.
Light allows photosynthesis to occur. Therefore more light=faster reaction.
Photosynthesis consists of two stages: a series of light-dependent reactions that are temperature independent and a series of temperature-dependent reactions that are light independent. The rate of the first series, called the light reaction, can be increased by increasing light intensity (within certain limits) but not by increasing temperature. In the second series, called the dark reaction, the rate can be increased by increasing temperature (within certain limits) but not by increasing light intensity.
Water is the molecule that is split during the light reaction of photosynthesis when releasing oxygen.

why light reaction of photosynthesis is essential before the dark reaction can procced?

Photosynthesis is not considered a synthesis reaction because it involves the conversion of light energy into chemical energy, rather than the direct combination of two or more substances to form a new compound.
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.
The 2 stages are light-dependent stage and the light-independent stage. In the light-dependent stage, photolysis of water 12H20 --------> 6O2 + 24H Light energy is converted to Chemical energy In the light-independent stage, enzyme controlled reaction 6CO2 + 24H -----------------> C6H12O6 + 6H20
Light allows photosynthesis to occur. Therefore more light=faster reaction.
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
Photosynthesis consists of two stages: a series of light-dependent reactions that are temperature independent and a series of temperature-dependent reactions that are light independent. The rate of the first series, called the light reaction, can be increased by increasing light intensity (within certain limits) but not by increasing temperature. In the second series, called the dark reaction, the rate can be increased by increasing temperature (within certain limits) but not by increasing light intensity.
There is the light-dependent stage, where sunlight interacts with choloropyll to set up an electron-transport chain, then there is the chemical stage, where glucose molecules are synthesized from CO2 and H2O.
