No, they move from photosystem 2 to photosystem 1. 2 evolved first but was not discovered until after photosystem 1.
Excited electrons are transferred to an electron transport chain.
They come from Photosystem ll. Photosystem ll gets them by ripping the electrons off of water by a process called photolysis. Electrons gain energy first in Photosystem ll, then later in photosystem l, through the absorption of energy from light.
Photosystem.
From energy in photons
No, they move from photosystem 2 to photosystem 1. 2 evolved first but was not discovered until after photosystem 1.
The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.

It's a pathway where electrons are transported from photosystem 2 to photosystem 1.

they move through an electron transport chain to photosystem 1
They return to Photosystem I
