Light Dependent Reaction
-
Chlorophyll in photosystem II absorbs light energy which excites electrons to a higher energy level, releasing them from chlorophyll
Some energy from electrons released during photoionisation is conserved in the production of ATP and reduced NADP
Electrons pass down electron transfer chain from PSII to PSI via redox reactions, losing energy at each step.

Protons move by facilitated diffusion down the electrochemical gradient into the storm via the enzyme ATP synthase embedded in the thylakoid membrane

- Production of reduced NADP
In PSI electrons are excited and transferred to NADP (with a proton from photolysis) to reduce NADP to form reduced NADP
Splitting of water sing light energy produces protons, electrons and oxygen (2H2O ->> O2 + 4e- + 4H+)
