Where do electrons come from and how it gains energy during the light reaction?
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.
Photosynthetic unit where solar energy is absorbed and high energy electrons are generated?
Photosystem.
How does electrons move photosytem II to photosytem?
No, they move from photosystem 2 to photosystem 1. 2 evolved first but was not discovered until after photosystem 1.
Where do electrons get their in photosystem I?
From energy in photons
Where do electrons get their get their energy in photosystem?
From energy in photons
How many times are electrons energized during photosynthesis?
The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.

What happens to electrons when pigments in photosystem II absorbs light?
they move through an electron transport chain to photosystem 1

From energy in photons
How do electrons gain energy in photosystem I?
They absorb photons.
What is the explanation for the pathway of electron transport chain?
It's a pathway where electrons are transported from photosystem 2 to photosystem 1.
Electrons from what replace the electrons from photosystem 2 during noncyclic electron flow?
water
Electrons from what replaces the electrons from photosystem 2 during noncyclic electron flow?
water
Which photosystem most likely envolved first?
Photosystem II most likely evolved first because it provides the energy for producing ATP and passes its electrons to photosystem I.
