3. •Light reaction includes a Photochemical phase.
It include light absorption, water splitting, oxygen release and
formation of high energy chemical intermediaries as ATP and NADPH
Pigments in this reaction is organized into light harvesting
complexes as PS I and PS II
Editor's Notes
Today we will study about light reaction in photosynthesis and the pigments involved in the light reaction.
The Light harvesting complex
PS I and PS II are the two main light harvesting complexes. The LHC is made of hundreds of pigment molecules bound to proteins.
