Refer to the diagram above When light is not present, DPIP is unalfected Nothing should have happened inside Ihe "Dark" cuvelle Why? WebWhen the DPIP accepts the electron, the compound begins to degrade. A greater concentration of DPIP is easily seen inside a cuvette because of the dark blue dye associated with the DPIP. As DPIP degrades, the color of the chloroplast solution begins to get lighter. A solution without DPIP would be clear.

WebComplex IV passes the electrons to O 2 _2 2 start subscript, 2, end subscript, which splits into two oxygen atoms and accepts protons from the matrix to form water. Four electrons are required to reduce each molecule of O 2 _2 2 start subscript, 2, end subscript, and two water molecules are formed in the process. WebReceived May 29, 1967. 2,6-Dichlorophenolindophenol (DPIP) is one of the many commonly used electron acceptors for the light-induced reactions in chloroplasts (2).
