Webb6 maj 2008 · A linear hydrogen-bonded chain of water molecules that can carry out proton transfer is termed a proton wire. The ability of protons to rapidly propagate along a proton wire involves jumping of protons from one water molecule to the next along the wire [ 4, 8 ]. Webbpump and leak components. Decreased pHi causes increased out-ward pumping of H+ ions, in a manner quantitatively consistent with their role as a substrate for the proton pump. This increased pumping is often manifest as a transient hyperpolarization at the onset of cytoplasmic acidification. With a considerably slower time flowitem bin flexsim

The proton pump is powered by the energy released when ATP is broken down into ADP and Pi. As the protons move out of the cell, they create a concentration gradient. The proton pump uses the concentration gradient to pump protons back into the cell.
