Light dependant reaction: phosphorylation (Thylakoid)
Light hits chlorophyll a, excites and releasing 2 electrons which travel down electron carriers. The energy given off is used to convert ADP + Pi into ATP.
1 of 7
Light dependent reaction: photolysis (Thylakoid)
A water molecule is split into oxygen, H+ ions and electrons. 2H2O--->4e+O2+4H+
2 of 7
Light dependent reaction: formation of NADPH (Thylakoid)
Electrons from the excitation of chlorophyll A hit chlorophyll B, leading to the release of 2 electrons. These travel down electron carriers, releasing energy, which along with the H+ ions from photolysis, reduce NADP to NADPH.

Light independent reaction: description
Known as the Calvin Cycle, the products of the light dependant reactions provide energy for this reaction, taking part in the stroma of the chloroplast. 6 cycles are required to produce 1 molecule of glucose(6C).
4 of 7
Light independant reaction: stage 1
Carbon dioxide reacts from the air with RuBP(5C) to produce 2 molecules of GP(3C).
5 of 7
Light independant reaction: stage 2
Using energy from ATP--->ADP+Pi, and H+ ions from NADPH---> NADP+H, Gp is reduced to 2 molecules of TP(3C).
6 of 7
Light independant reaction: stage 3
1C is given off to form carbohydrates such as glucose(6C), and the 5C molecule produced is RuBP.
