Electron transport in photosynthesis is a series of steps to generate ATP, starting with an electron coming from hydrolyzed water to replace a lost electron in chlorophyll of photosystem II. By number, put the following four steps in order to summarize the movement of this electron. 1) The electron-acceptor molecule transfers the electrons along a series of electron-carriers to photosystem I 2) Ferrodoxin transfers the electrons to NADP+ to form NADPH 3) In photosystem II, light excited electrons move from chlorophyll to an electron-acceptor molecule in the thylakoid membrane 4) Photosystem I transfers the electrons to a protein complex
