Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water.
For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.

∙ 13y agoPhotopigments release energy when they come into contact with light. This causes a second messenger system in the cell to send the sensation of a certain color of light.
the photopigment chlorophyll, when absorbing a photon, gets an electron knocked out of orbit by it. This electron follows an electron transport system which is the first step in the photosynthetic creation of energy in the form of ATP
I'm still trying to figure out what happens to the photopigment melanin when it absorbs a photon, so far i can only tell that heat gets dissipated, though there is evidence that different types of melanin will induce apoptosis (early stage cell death) in surrounding cells.

∙ 13y agoWhen chlorophyll or accessory pigments absorb photons it causes the electrons from chlorophyll A to be picked up by an acceptor molecule and sent through the cytochrome system. Electrons from chlorophyll B and accessory pigments replace the electrons of chlorophyll A.

∙ 14y agoChlorophyll is a pigment found in plants.
When photon is incident on chlorophyll, it gets excited so to speak and release electron to high energy state. The excited electron is then captured by different electron carriers.

∙ 11y agoPigments absorb light energy. The energy makes their electrons spin faster. In chlorophyll an electron gets so much energy that it is flung out of its orbit and can be "grabbed" by a protein to be passed along and carry the energy further.

What happens to a photon when it hits a leaf?
the photon's energy is either reflected green (because its a leaf) or its absorbed red, because red is the opposite of green and the red is not seen.
When a pigment molecule absorbs a photon one of its electrons?
the outer electrons which are weakly attracte towards nucleus of a pigment can absorb a photon and gets exited to its unstable higher levels. It releases more energy when it gets stabilized to its normal state. This energy can be trapped by the electron of next pigment molecules. In this way the energy gets transfered from one to other.
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.
Light travels to plants as tiny packets of radiant energy called?
photon
What is the term for the particles of light that provide the energy needed for photosynthesis?
Photon
What happens to an atom when it loses an electon?
they jump to a higher energy level
Why is glass transparent?
When the electrons in molecules are unable to absorb the energy of incident photon, the photon continues along its path. This happens in the case of glass, even though glass is not 100 percent transparent, as some of the photon energy is absorbed by the glass electrons.
What pigment molecules absorb a photon and pass the energy to the reaction-center complex?
chlorophyll
Can the electron in the ground state of hydrogen absorb a photon of energy 13.6eV and greater than 13.6eV?
yes , the electron in the ground state of the hydrogen atom will absorb a photon of energy 13.6ev but not greater than 13.6 ev . because 13.6 ev is the energy which excites the hydrogen atom
What determines which photon an atom can absorb or emit?
Generally if they are of the same wavelength, then the atom will absorb the photon at that wavelength.
Can free electron absorb photon?
a free electron may absorb a photon only if its parity changes
What happens if the energy of a photon exceeds that necessary for pair production?
The excess energy is transferred to the particles as kinetic energy.
When sunlight excites electrons how do the electrons change?
Depending 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.
Which best explains how green plants absorb energy from the Sun?
A photon strikes electrons in special molecules in the cells.(APEX)
If an electron is in an excited state it must lose energy when it falls to a lower state. What happens to the energy that is lost?
This energy is released as a photon.
How light is absorb?
By the agitation of an electron by a photon.
What happens when photon is absorbed by atom?
When an atom absorbs a photon its energy is transferred to outer shell electrons. The result will be the transition of an electron to a higher energy state.
