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.
ATP is important because when it breaks down to form ADP and in turn AMP, the phosphate groups may be transferred to other molecules making them 'more reactive' and making che â¦ mical change more likely. For example ATP provides energy for chemical change in the liver or the retina of the eye for making visual pigments.
