Photophosphorylation The electron transport system is found embedded within the thylakoid membrane and functions in the production of ATP. The system contains membrane-bound electron carriers that pass electrons from one carrier to another. As a result of gaining an electron (reduction), the first carrier of the electron transport system gains energy. It uses some of the energy to pump H + into the thylakoid. The carrier then passes the electron to the next carrier. Because it used some energy to pump H + , it has less energy (reducing capability) to pass to the next H + pump. This carrier uses some of the remainder of the energy to pump more H + into the thylakoid. The electron is passed to the next carrier which also pumps H + .

The electron transport system functions to create a concentration gradient of H + inside the thylakoid. The concentration gradient of H + is used to synthesize ATP. ATP is produced from ADP and P
