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 \(\PageIndex{1}\) ).The absorption of a single photon or distinct quantity or “packet” of light by any of the chlorophylls pushes that molecule into an ...

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).
Jul 31, 2022 · 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). Figure 5.
A photon of light energy travels until it reaches a pigment molecule, such as chlorophyll. The photon causes an electron in the chlorophyll to become “excited.” The energy given to the electron then travels from one pigment molecule to another until it reaches a pair of chlorophyll a molecules called the reaction center. This energy then ...

When a chlorophyll a molecule within the reaction center of PSII absorbs a photon, the electron in this molecule attains a higher energy level. Because this state of an electron is very unstable, the electron is transferred to another molecule creating a chain of redox reactions called an electron transport chain (ETC).
