# Overview of Chemiosmotic hypothesis
Abstract: An important part of photosynthesis is chemiosmotic theory or hypothesis . We have already learn electron transport chain. When the electron passes from it , it then releases energy and this energy used for the synthesis of ATP. Here I simply discuss the matter but the original phenomenon is quite complicated let's draw a thylakoid. It is an outer membrane and an inner membrane. The cavity is known as lumen. The water splitting complex is present in the the inner membrane . Thylakoid On the bottom of PS II there is chlorophyll reaction center and the top is primarily electron acceptor and then electron is going to pass from PS II to PS I through cytochrome . When the sunlight fall on PS II then the electron are activated and now electron pair is passing through cytochrome and finally go to the PS I this electron is going to higher level to lower level. It release energy at the cytochrome. It reveals that energy when the electron transport the electron from...
