Excited electrons are transferred to an electron transport chain.
Excited electrons are transferred to an electron transport chain.
Electron Transport System
NADH and FADH are Coenzymes which act as carriers of electrons, protons, and energy in metabolism.
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
they move through an electron transport chain to photosystem 1
They go into photosystem I.
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.
Photosystem I
Light energy is not exactly trapped. The light energy excites the electron in the reaction centres of photosystem I and photosystem II. The electron excites and transfers to the electron transport chain ( chain of electron carriers), this produces ATP. Then the electron of photosystem II is transferred by photosystem I and the electron of the photosystem I is used with H+ and NADP to form NADPH. Photosystem II gets back an electron from photolysis of water.

They go into photosystem I.
It's a pathway where electrons are transported from photosystem 2 to photosystem 1.
