When light is absorbed by chlorophyll molecules the excited electrons leave the molecule What is the source of electrons that makes chlorophyll stable again?

Additional electrons used to stabilize the photosystems come from photolysis, the splitting of water using photons of light. This process yields 2 electrons per molecule of water.

What a pigment molecule that transfers electrons during light reaction?
The chlorophyll molecule.
What color of light is reflected by the chlorophyll molecule?
Green, red and blue are absorbed
What happens when light hits a pigment?
When a chlorophyll molecule absorbs a photon of light, Photons strike the "antenna" of the chlorophyll molecule. This causes electrons in the photo-reaction centers that are attached to the antennas to become excited and move to a higher energy level. That's photoexcitation. The valence electrons in Magnesium (part of the chlorophyl molecule) jump to an excited state.
When molecules are formed atoms share or loose electrons?
To form a molecule, atoms can share, lose, and gain electrons
What is molecules is polar?
Non-polar molecules are not charged.
When energy absorbed by one type of chlorophyll molecule is used to form molecules of ATP electrons from a second kind of chlorophyll molecule are used?
in forming molecules of NADPH
How does light energize a chlorophyll a molecule?
Light is absorbed by the chlorophyll.
What has to happen to replace the electrons released by chlorophyll?
Electrons are replaced with splitting water when light strikes chlorophyll.
Electrons that have been excited by light energy absorbed by a chlorophyll molecule?
Some of the electrons become excited. means that they have comparatively more energy. the flow of energy takes place through these excited electrons. these are transferred form the reaction center chlorophyll to the primary electron acceptors.
Explain what happens when sunlight hits a chlorophyll molecule?
As the sunlight hits the chlorophyll molecules sunlight is absorbed by a molecule of chlorophyll electrons in the molecule interact with photons of light and are raised to a higher energy level. The electrons are passed from one molecule to another in an electron transport chain producing ATP and NADPH. In case you don't know ATP is what cells mainly use for energy and NADPH is use as an electron carrier.Light energy is transferred to the electrons inthe chlorophyll molecule, raising the energy of theseelectrons. These high-energy electrons make photosynthesiswork.100% correct answer. Got it from answer book :D. You might want to change some words though since I got it straight from answer book...Its 9th grade biology btw
What a pigment molecule that transfers electrons during light reaction?
The chlorophyll molecule.
What gathers the sun's energy with light-absorbing molecules called pigments?
the molecule chlorophyll
What happens when a photon from sunlight strikes a chlorophyll a molecule?
When a photon strikes a pigment molecule such as chlorophyll, the energy from the photon is passed to the chlorophyll. This energy then continues to pass between molecules until it hits the reaction center, where the reaction of photosynthesis' glucose creation occurs.
What is the first most immediate thing that happens when light strikes a chlorophyll molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
What is chlorophyll and what is it's role in photosynthesis?
Chlorophyll is a molecule found in chloroplast. When chlorophyll absorbs light, much of the energy is transferred directly to electrons in the chlorophyll molecule, raising the energy levels of these electrons. These high energy electrons make photosynthesis work.
What color of light is reflected by the chlorophyll molecule?
Green, red and blue are absorbed
