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.
What molecule absorbs sunlight in photosynthesis?
Photosystem II
What happens in a photosystem?
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.
What occurs to water molecules as a result of the actions of photosystem II?
They are split into oxygen and hydrogen.
Which molecule is split apart in photosynthesis II?
Water molecule
Where do the antennae in Photosystem II get the energy to split a water molecule?
Light from the sun

What groups of molecule are involved in photosynthesis?
Photosystem
What molecule absorbs sunlight in photosynthesis?
Photosystem II
Explain how oxygen is generated in photosynthesis?
oxygen is generated when two molecule of water are split to provide electrons lost by photosystem II so that the process of photosynthesis can continue progressively.
Which molecules is split apart in photosystem II?
Water. H2O.

After light hits photosystem I its energy is used to produce what molecule?
NADPH
What occurs to water molecules as a result of the actions of photosystem II?
They are split into oxygen and hydrogen.
Why is P680 of photosystem II said to be the strongest biological oxidizing agent?
This molecule results from the transfer of an electron to the primary electron acceptor of photosystem II and strongly attracts another electron.
Which molecule is split apart in photosynthesis II?
Water molecule
What specialized pigment molecule found at the center of every photosystem unit is absolutely essential to photosynthesis?
Chlorophyll A :)
