The truly interesting thing about these processes is that they are conserved across evolution. Anonymous. Each enzyme complex carries out the transport of electrons accompanied by the release of protons in the intermembrane space. The electron transport chain activity takes place in the inner membrane and the space between the inner and outer membrane, called the intermembrane space. Quit using the tricarboxylic acid cycle. In each reaction, when a molecule donates an electron it is said to be oxidized and the electron acceptor is said to be reduced. These carriers can pass electrons along in the ETS because of their redox potential. The electrons are passed through a series of redox reactions, with a small amount of free energy used at three points to transport hydrogen ions across a membrane. (i) The effective nuclear charge can be thought of as the true nuclear charge minus a screening constant due to the other electrons in the atom.
