During the process a protongradient is built up setting up a plasma membrane potential with or without companion movement of other ions. A common feature of all electron transport chains is the presence of a proton pump to create a transmembrane protongradient.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These motors are powered by the protongradient across the membrane. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The oxidation process involves the generation of a protongradient on the intracytoplasmic face of the anammoxasome. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These bacteria use the energy of light to create a protongradient using a photosynthetic electron transport chain. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Nitrate is taken up by several nitrate transporters that use a protongradient to power the transport. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This transport process is driven by a protongradient between cell organelles and the cytoplasm. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The protongradient is used to produce useful work. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Some terminal oxidases generate a transmembrane protongradient across the plasma membrane (prokaryotes) or the mitochondrial inner membrane (eukaryotes). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. At the same time, four protons are removed from the mitochondrial matrix (although only two are translocated across the membrane), contributing to the protongradient. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Both the direct pumping of protons and the consumption of matrix protons in the reduction of oxygen contribute to the protongradient. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The protons are released into the thylakoid lumen, thus contributing to the generation of a protongradient across the thylakoid membrane. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It recovers energy for the cell by funneling electrons into the respiratory chain and by increasing the protongradient. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The transfer of electrons is coupled to the translocation of protons across a membrane, producing a protongradient. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These also produce a protongradient, but in a quite different and more indirect way involving an electron transfer chain consisting of several other proteins. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Since the middle of the 1970s, his lab has studied the biochemistry of bacteriorhodopsin, a membrane protein that converts light energy into chemical energy by creating a protongradient. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This means that these reactions are readily reversible, by increasing the concentration of the products relative to the concentration of the reactants (for example, by increasing the protongradient). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Here, proton gradients are used to drive secondary transport processes.
