The function of the reaction center of chlorophyll is to absorb light energy and transfer it to other parts of the photosystem. The absorbed energy of the photon is transferred to an electron in a process called charge separation. The removal of the electron from the chlorophyll is an oxidation reaction. See more Chlorophyll (also chlorophyl) is any of several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants.

WebMar 30, 2024 · Chlorophyll transforms into a molecule called pheophytin. As a result, pheophytin absorbs and reflects light differently than chlorophyll. Instead of vibrant green, it is a dull green color. When the magnesium ion (Mg 2+) has been replaced by two hydrogen (H) atoms, the molecule loses its bright green color. WebThese reactions occur in two stages: the “light” stage, consisting of photochemical (i.e., light-capturing) reactions; and the “dark” stage, comprising chemical reactions controlled by enzymes. ff5457

However, chlorophyll is not a very stable compound; bright sunlight causes it to decompose. To maintain the amount of chlorophyll in their leaves, plants must continuously synthesize it, but this requires sunlight and warm temperatures.
