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.

Are excited electrons from the acceptor molecule sent to the electron transport chain?
Yes!
When the electrons of an excited atom fall back to lower levels there is an emission of energy that produces what?
The electrons emit photons of light equal in energy to the energy that was absorbed.
When one electron moves from the 4th shell to the 2nd shell in hydrogen is energy absorbed or emitted by the atom?
The energy is absorbed by the electrons because work needs to be done on the electrons to raise them to an excited state. Energy is stored in the electrons while they are in their excited state and would emit energy if they returned to their ground state.
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.
Why do molecules absorb light?
Molecules absorb light because of what light does to their electrons. It can cause a molecule's electrons to become excited and then changes from a full shell to an anti-bonding shell depending on how much light is absorbed.
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 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.
When sunlight excites electrons in the chlorophyll how do the electrons changes?
As red and blue light energy is absorbed by Chlorophyll electrons in outer shell are excited & raised to a higher energy level.
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.
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.
What is the first most immediate thing that happens when light strikes chlorophyl molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
What gets excited when chlorophyll absorbs a photon?
electrons
What causes the electrons to become excited and move into the electron transport chain?
In photosynthesis, the electrons from the chlorophyll are excited by the sunlight
What is the reaction when chlorophyll donates excited electrons?
the reaction center.
A molecule of chlorophyll increases in potential energy?
when one of its electrons is boosted to a higher-energy excited state upon being struck by a photon of light.
When sunlight excited electrons in chlorophyll how do the electrons change?
the electrons gain a huge amount of energy
The state of matter in which electrons have absorbed energy is called?
Excited Electrons
