The electron transport chain is a system of molecules through which electrons are transferred to generate ATP. It has an important role in both photosynthesis and cellular respiration. ETS in photosynthesis. In photosynthesis, when you are absorbed in photosystem 2, electrons are energized.here are a number of molecules that consists an electron transport chain. Most of these molecules are proteins, built into the inner membrane of mitochondria of eukaryotic cells and the plasma membrane of aerobically respiring prokaryotes.
Report Abuse. Oxygen is the final acceptor of electron in the electron transport chain. The transfer of electrons pumps proton across the inner mitochondrial membrane and this gradient is used to synthesize energy in the form of ATP. Source(s): Personal knowledge.s a result, aerobic respiration can generate up to 19 times more ATP per molecule of glucose than lactic acid fermentation. Why Oxygen Is Important: Oxygen is important because it makes aerobic respiration possible by accepting electrons from the transport chain in the mitochondria.
