donating electrons to photosystem II
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II. Photosystem I and photosystem II both contain chlorophyll as molecules.
Light
The initial reactions in photosynthesis are the light dependent reactions and the light independent reactions
Light Reactions and the Calvin Cycle Reactions.
The pigment directly involved is the green pigment called 'chlorophyll' and is found in the chloroplats.
light dependant reactions
Pigments in chloroplasts absorb light energy in the form of photons during the light reactions of photosynthesis.
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.
In photosynthesis, the light reactions converts the sunlight int chemical energy (ATP molecules, NADH+H). Dark reactions (light independent reactions) do not use sunlight directly, but use energy stored in ATP and NADH molecules combined with CO2 to produce sugars.

There are two reactions. Those are light dependent and independent.
