Oct 16 Light Dependent Reactions










This process is called noncyclic photophosphorylation.

Difference between Photosystem 2 and Photosystem 1. Ps2 has a water splitting enzyme while Ps1 does not. Also the wavelengths of the reaction center are slightly different.


E. These electrons are now passed down a 2nd electron transport chain of cytochromes and are finally transferred onto NADPH (serves as an intermediate electron acceptor). These electrons will now be transferred, in the light-independent reactions onto Glucose.

Reaction
*NADP+ + H+ + 2e- ------> NADPH * must have this equation memorized.
