The role of photosynthesis II is the generation of ATP along with splitting of the water molecules. The electron transfer, is another function of photosynthesis II.
A water molecule is split into hydrogen and oxygen
Photosystem 2 happens in photosynthesis before photosystem 1. However they are numbered in order of how they were discovered. Photosystem 1 was discovered before photosystem 2. In photosynthesis the order of them is 2 then 1. meaning that photosystem 1 was discovered 1st but photosystem 2 happens 1st in photosynthesis
When an excited electron is passed to an electron acceptor in a photosystem, energy in sunlight is transformed to chemical energy.
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
Photosystem 1 and Photosystem 2
No, they move from photosystem 2 to photosystem 1. 2 evolved first but was not discovered until after photosystem 1.

they move through an electron transport chain to photosystem 1
Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.
When an excited electron is passed to an electron acceptor in a photosystem, energy in sunlight is transformed to chemical energy.
- ATP is the end result after Photosystem II. - NADPH is the end result for Photosystem I. They are sources of energy & they use sugars for energy storage/transport.
Photosystem 1
solar energy changes adp into atp.
1. Photosystem I is found in the membrane facing the inside of the grana and Photosystem II is found in membrane facing the stromaTHYLAKOID MEMBRANE
Photosystem I or the p700 complex is used last in photosynthesis.
NADPH
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
