Uses both
Photosystem 1 and photosystem 2
Electrons pass from what to what
from H2O to NADP+
How many steps are there
four
Light what electron in what and then transferred to what
Light EXCITES electron in PHOTOSYSTEM 1 and then transferred to NADP+
NADP+ + 2electrons + 1H+ → NADPH
the electron what in what is replaced by an what from what
The electron “HOLE“ in PHOTOSYSTEM 1 is replaced by an ELECTRON from PHOTOSYSTEM 2
The what that is absorbed by what is transferred to what and the free what is transferred down the what to the what in what. The what released along what is used to make what
The LIGHT ENERGY that is absorbed by PHOTOSYSTEM 2 is transferred to CHLOROPHYLL and the free ELECTRON is transferred down the ETC to the “HOLE“ in PHOTOSYSTEM 1. The ENERGY released along ETC is used to make ATP
The what in what is then filled by the what of water, providing what
The ELECTRON HOLE in PHOTOSYSTEM 2 is then filled by the PHOTOLYSIS of water, providing ELECTRONS
2H2O (l) + Light energy → 4H+ + 4electrons + O2 (atmospheric)
