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.
Electron carriers are important molecules in biological systems. They accept electrons and move them as part of the electron transport chain, transferring the electron, and the energy it represents, to power the cell. Electron carriers are vital parts of cellular respiration and photosynthesis.ytochrome C is important at the end of the electron transport chain in the mitochondria, or in bacterial cells, which do not have mitochondria. Cytochromes are proteins forming a matrix around an iron atom, known as the heme group.
