What Is The Electron Carrier Molecule Of Photosynthesis?

Aug 22, 2016  · To put it simply: in the electron transport chain the movement of electrons is used to pump hydrogen atoms (#H^+#) to one side of the thylakoid membrane (inside chloroplasts of plants). At the end of the transport chain the #H^+# atoms flow from high concentration to low concentration which fuels the enzyme ATP synthase.
