When sunlight excites electrons in chlorophyll how do the electrons change?

When a chlorophyll molecule absorbs light, the process of photosynthesis, or the transfer of light into sugar, begins. Chlorophyll is a green liquid inside one part of a plant cell: the chloroplast.
When light hits the chlorophyll molecule, it becomes excited. This energy passes through other chlorophyll molecules, and into the reaction center of Photosystem II: this is the location of the first stage of photosynthesis, and the electron transport chain.
For each photon of light that enters and excites a chlorophyll molecule, one electron is released from the reaction center of Photosystem II. When two electrons are released, they are transferred to Plastoquinone Qb, a mobile carrier, which picks up two protons and starts moving towards the Cytochrome b6f complex. Cytochrome b6f, like Photosystem II, is a complex where photosynthesis processes occur.

∙ 11y agoDepending on the energy (frequency) of the specific photon hitting the electron, one of three events happens: nothing, the electron is excited, or the electron leaves the atom.
If the energy of the photon very high, the electron can absorb the energy and escape the nucleus' pull. This is called ionization.
If the energy of the photon lines up with the energy spacing in the atoms energy levels, the electron will move to a higher energy state, becoming excited. The electron then returns to its original energy level, releasing the energy as light.
If the energy of the photon does not fall into one of these categories, the electron does not interact with it.
In terms of actually changing the electron, it only changes in energy, not any other property.

Is leaves turning color in the fall a chemical or physical change?
I don't know the scientific equation, but I do know that the tree withdraws it's sugars from the leaves, during the autumn and winter to make sure that there is enough for the main tree. The withdrawal of the sugars is a physical action, but it is a chemical one as well. The chlorophyll that was made thru the sunlight on the leaves for photosynthesis. This stops when the weather turns colder and there is less sunlight causing the leaves lessen the amount to chlorophyll they can make, signaling to the tree to cut off the sugar supply to the leaves. I'd say it's both. Also, You have witnessed a spectacular chemical change if you have seen the leaves on a tree change from green to bright yellow, red, or orange. But, it is not a change from a green pigment to a red pigment, as you might think. Pigments are chemicals that give leaves their color. In autumn, however, changes in temperature and rainfall amounts cause trees to stop producing chlorophyll. The chlorophyll already in the leaves undergoes a chemical change into colorless chemicals.Where do the bright fall colors come from? The pigments that produce fall colors have been present in the leaves all along. However, in the summer, chlorophyll is present in large enough amounts to mask these pigments. In the fall, when chlorophyll production stops, the bright pigments become visible.
Is sunlight speeding up the evaporation of a bowl of water a chemical change?
No. It is a physical change.
What change in colour is observed when a silver chloride is left exposed to sunlight?
The colour will change into grey.
Why is it a chemical change when the leaves turn different colors in the fall?
As plants receive less sunlight, they change color. They are green because they have a lot of sunlight and are able to produce glucose and other energy chemicals. The less sunlight they receive, the less chemicals they produce.
Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
Electrolysis of water is a chemical change. Exposing sodium chloride to sunlight would cause some heating, but no chemical changes.
When sunlight excites electrons in chlorophyll how do electrons change?
As red and blue light energy is absorbed by Chlorophyll electrons in outer shell are excited & raised to a higher energy level.
When sunlight excited electrons in chlorophyll how do the electrons change?
the electrons gain a huge amount of energy
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
How tree with red leaves get food?
in green plants chlorophyll traps sunlight ,by which photosynthesis takes place.but in red leaves there is a pigment act as chlorophyll or pigment which cause change in colour.
Why leaves have green color?
Leaves are green because they contain a green-coloured pigment called chlorophyll. Chlorophyll allows the leaves to capture sunlight and change it from light energy to chemical energy during photosynthesis.
Why cant leaves change color in the winter?
the pigment chlorophyll inside the leaves are what give the leaves their color. They "feed" off of sunlight and in the winter there is less sunlight and can't keep the green color.
Is O2 a reactant in photosynthesis?
The equation for photosynthesis is: 6CO2 + 12H2O → C6H12O6 + 6O2 + 6H2O This could be simplified to (and is usually seen as): 6CO2 + 6H2O → C6H12O6 + 6O2. From the equations above, it could be seen that sunlight is not a reactant in photosynthesis. Reactants are substances that takes part in and undergoes change during a reaction. Sunlight does not; hence sunlight is not a reactant in photosynthesis.
Does cholorophyll havve carbon?
No chlorophyll doesn't contain carbon.rather,it absorbs or traps energy from sunlight to transform or change carbon dioxide and water to carbohydrate and oxygen.
What contains chlorophyll which is the main ingredient the plant uses to change sunlight into food for the plant?
Chlorophyl contains chloroplast , a green coloured one that absorbs the sun light.
How do plants have photosynthesis?
Photosynthesis is the change of light energy into chemical energy. Plants use the sunlight, the soil, the water to make a substance known as chlorophyll (this keeps leaves green). This is like the plant's food.
What are the causes of color change of leaves?
sunlight, heat, viruses, season change, mutations, lack of nutrients... and many moreAnswerAs autumn gets colder the tree retrieves the nutrients from its leaves, no sense in leaving them behind. The first to get re-absorbed is the chlorophyll leaving behind the red photosynthetic pigment.
What cause leaves to change color?
chlorophyll
