Once extracted from the protein into a solvent (such as [[acetone]] or [[methanol]]), these chlorophyll pigments can be separated in a simple paper chromatography experiment, and, based on the number of polar groups between chlorophyll a and chlorphyll b, will chemically separate out on the paper.
 
The function of the reaction center chlorophyll is to use the energy absorbed by and transferred to it from the other chlorophyll pigments in the photosystems to undergo a charge separation, a specific [[redox]] reaction in which the chlorophyll donates an [[electron]] into a series of molecular intermediates called an [[electron transport chain]]. The charged reaction center chlorophyll (P680<sup>+</sup>) is then reduced back to its ground state by accepting an electron. In Photosystem II, the electron which reduces P680<sup>+</sup> ultimately comes from the oxidation of water into O<sub>2</sub> and H<sup>+</sup> through several intermediates. This reaction is how photosynthetic organisms like plants produce O<sub>2</sub> gas, and is the source for practically all the O<sub>2</sub> in Earth's atmosphere. Photosystem I typically works in series with Photosystem II, thus the P700<sup>+</sup> of Photosystem I is usually reduced, via many intermediates in the thylakoid membrane, by electrons ultimately from Photosystem II. Electron transfer reactions in the thylakoid membranes are complex, however, and the source of electrons used to reduce P700<sup>+</sup> can vary. The electron flow produced by the reaction center chlorophyll pigments is used to shuttle H<sup>+</sup> ions across the thylakoid membrane, setting up a [[chemiosomosis|chemiosmotic]] potential mainly used to produce [[Adenosine triphosphate|ATP]] chemical energy, and those electrons ultimately reduce NADP<sup>+</sup> to [[NADPH]] a universal [[redox|reductant]] used to reduce CO<sub>2</sub> into sugars as well as for other biosynthetic reductions.
