Electron transport chain: 1

1. Electrons move down the electron transport chain , releasing energy that pumps hydrogen ions into the thylakoid space. 2. Hydrogen ions diffuse across the thylakoid membrane into the stroma through ATP synthase. 3. Energy from the Sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions. The concentration of ... Compare and contrast the electron transport chain in photosynthesis and cellular respiration Get the answers you need, now! Answer: (B) Electron transport chain will be the correct answer Explanation: The electron transport chain is a s equence of redox processes that occur during cellular respiration, as well as subsequent stages of glycolysis and the citric acid cycle where glucose metabolism can utilize ambient oxygen. Electron carriers predominantly decrease oxygen in the presence of glucose as a prerequisite during glycolysis and the citric acid cycle, and following this ETC process, water molecules are ... Oxygen acts as the final electron acceptor in the electron transfer chain , resulting in the formation of H 2 O. This is essential because without it, the electron transfer chain cannot function resulting in a lack of oxidative phosphorylation in the inner membrane of the mitochondria. Further more, the lack of functioning electron transport chain means that NADH and FADH 2 cannot be oxidised, creating a lack of NAD+ and FAD, which are coenzymes for reactions in the Link reaction and the ...
