Plant Pigments and Photosynthesis Lab Report Plant Pigments and Photosynthesis Lab Report Photosynthesis, in a nutshell, is the process that allows plants to capture the sun’s energy and store it as chemical potential energy in the bonds of carbohydrate molecules. There are two processes in which this takes place, called Photosystems. In Photosystem I, light from the sun travels into the chloroplast and goes through the antennae pigment, into the reaction center. The light that travels into the first reaction center is called P700. An electron is then sprung out of the reaction center into the e- transport train, or the cytochrome system. The electron is then taken to NADP+. The NADP+ is then reduced into NADPH. After the loss of the electron from P700, the P700 can no longer function. Photosystem II is then needed. The antennae pigment of Photosystem II absorb light energy of P680. The pigment is exited and transfers this absorbed energy to an electron, causing it to break free, and travel to other electron transport molecules until it reaches P700, replacing its lost electrons. The lost electrons of P680 are replaced by extracting electrons from two water molecules. That leaves four hydrogen ions, that are released into the Thylakoid space, and combine light, cuvette, put, energy, chloroplasts, pigment, through, solvent, photosynthesis, table, electron, data, after, added, water, un-boiled, transmittance, top, spectrophotometer, reactions, paper, p700, out, occur, needed, lab, first, each, drops, chloroplast, bottom, atp, work, two, same
