Photosynthesis ;
It is well evident now that the process of photosynthesis consists of the following two steps:
1. Light reaction :
It is also called Hill reaction, photosynthetic electron transfer reaction or photochemical reactions.
In light reaction solar energy is trapped in the form of chemical energy of ATP and as reducing power in NADPH.
During it, oxygen is evolved by photolysis or splitting of water molecule.
Light reaction occur in thylakoid membrane.
2. Dark reaction :
It is also called Calvin reaction, photosynthetic carbon reduction cycle (PCR cycle), carbon-fixation reaction or thermo-chemical reaction.
In dark reaction, the reducing capacity of NADPH and the energy of ATP are utilized in the conversion of carbon dioxide to carbohydrate.
Such a process of "carbon fixation" occurs in the stroma of chloroplast.
