Photosynthesis light dependant stage and pigments

Photosynthesis

Light dependant reaction

1) light strikes the chlorophyll in photo system 2 this excites the electrons and boosts them to a higher energy level

2) the electrons are accepted by an electron carrier in the thylokoid membrane (NADP becomes reduced)

3) The oxidised chlorophyll then removes electrons from water producing protons and oxygen  this occurs in the thylokoid membrane

4) as the electrons pass between the carriers they lose energy , this energy is then transferred to the proton pumps.The Protons are then pumped from the stroma to…
