A mobility shift assay is electrophoretic separation of a proteinâDNA or proteinâRNA mixture on a polyacrylamide or agarose gel for a short period (about 1.5-2 hr for a 15- to 20-cm gel).
In the mitochondrial electron transport chain electrons move from an electron donor (NADH or QH 2) to a terminal electron acceptor (O 2) via a series of redox reactions. These reactions are coupled to the creation of a proton gradient across the mitochondrial inner membrane.he function of the electron transport chain is to produce a transmembrane proton electrochemical gradient as a result of the redox reactions. If protons flow back through the membrane, they enable mechanical work, such as rotating bacterial flagella.
