Webas iron oxides. In the proper geometry, iron oxide clusters can behave like a compass needle and magnetic bacteria use such a compass needle mechanism to find up and down. An alternative possibility is to use short-lived, specialized photochemical reac-tions, for which thermal noise does not have time to effectively mask effects of magnetic fields. WebIn the dark, cryptochrome is found with flavin in the oxidized state (FAD) which, upon irradiation, undergoes reduction to the FADH ℴ form. This reaction requires both electron …
