When light energy is absorbed by PSI, electrons are re-energized, either returning to the ETC to pump more H+ or, in non-cyclic photophosphorylation, forming NADPH2 by combining with NADP+ and H+.
- 2e- reenergised EITHER - returns to ETC - another H+ actively transported OR - non-cyclic photophosphorylation - NADP + 2e- + 2H+ --> NADPH2
