The Excited State of a Chlorophyll Molecule When a photon of light hits chlorophyll, the electrons becomes excited and jump to a higher (more energetic) electron shell. If the chlorophyll is isolated, the electron quickly returns to is original state, releasing heat and fluorescence.

A photon of light energy travels until it reaches a molecule of chlorophyll. The photon causes an electron in the chlorophyll to become “excited.” The energy given to the electron allows it to break free from an atom of the chlorophyll molecule. Chlorophyll is therefore said to “donate” an electron (Figure 5.12).
When chlorophyll a absorbs light energy, an electron gains energy and is 'excited'. The excited electron is transferred to another molecule (called a primary electron acceptor). The chlorophyll molecule is oxidized (loss of electron) and has a positive charge.Nov 25, 2021
During the light-dependent stage (“light” reactions), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of NADPH (an enzyme) and high-energy ATP molecules.
Sunlight is absorbed by photosynthetic pigments, the most abundant of which in plants are the chlorophylls. Absorption of light excites an electron to a higher energy state, thus converting the energy of sunlight to potential chemical energy.
- Light energy is used to excite electrons on specific chlorophyll molecules.
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.Sep 13, 2019
The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced. ... The two photosystems absorb light energy through proteins containing pigments, such as chlorophyll.Dec 10, 2018
What does light do when it strikes the chlorophyll molecules of photosystems I and II? After light excites electrons and they leave Photosystem II to travel down the first electron transport chain.
Water, when split, gives oxygen, hydrogen, and electrons. These electrons move through structures in chloroplasts and, by chemiosmosis, make ATP. The hydrogen is converted to NADPH, which is then used in the light-independent reactions. ... This all happens in the grana thylakoid of chloroplasts.
Photosynthetic eukaryotes and cyanobacteria have two photosystems – Photosystem II and Photosystem I. Light energy causes the excitation and loss of an electron from a PSII reaction center chlorophyll (P680). Water is oxidized to replace the lost electron, generating H+ ions and oxygen (O-2) ions.
light is absorbed increasing the energy of the electrons. the electrons are passed down the electron transport chain. electrons are passed from protein to protein to protein releasing energy. The energy is used to pump H+ ions from the stroma into the thylakoid space.
A photon of light hits chlorophyll, causing an electron to be energized. The free electron travels through the electron transport chain, and the energy of the electron is used to pump hydrogen ions into the thylakoid space, transferring the energy into the electrochemical gradient.
