What else can I help you with?
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.
When during the light reaction is the water molecule split?
The water molecule is split at the beginning of the light reaction, specifically in photosystem II. This splitting of water releases electrons, protons, and oxygen as byproducts, which are essential for the rest of the light-dependent reactions to occur.
What molecule absorbs sunlight in photosynthesis?
Photosystem 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

They are split into oxygen and hydrogen.
Which is produced using energy from photons hitting photosystem ll?
ATP and NADPH are produced using energy from photons hitting photosystem II. These molecules are essential in the light-dependent reactions of photosynthesis to drive the production of sugars.
After light hits photosystem I its energy is used to produce what molecule?
NADPH
Which molecules is split apart in photosystem II?
Water. H2O.
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 :)
Electrons are excited in photosystem 1 what do these electrons combine with in order to produce an energy-carrying molecule?
NADP+
