The gradient of electrochemical potential
An electrochemical gradient is a gradient of electrochemical potential, usually for an ion that can move across a membrane. The gradient consists of two parts, the chemical gradient, or difference in solute concentration across a membrane, and the electrical gradient, or difference in charge across a membrane. … See more Electrochemical energy is one of the many interchangeable forms of potential energy through which energy may be conserved. It appears in electroanalytical chemistry and has industrial applications such as batteries and fuel … See more The generation of a transmembrane electrical potential through ion movement across a cell membrane drives biological processes See more Proton gradients in particular are important in many types of cells as a form of energy storage. The gradient is usually used to drive ATP synthase, flagellar rotation, or metabolite transport. This section will focus on three processes that help establish … See more The term typically applies in electrochemistry, when electrical energy in the form of an applied voltage is used to modulate the See more Since the ions are charged, they cannot pass through cellular membranes via simple diffusion. Two different mechanisms can transport the ions across the membrane: See more • Concentration cell • Transmembrane potential difference • Action potential • Cell potential See more WebThis gradient represents a stored form of energy, and, as we’ll see, it can be used to make ATP. Chemiosmosis Complexes I, III, and IV of the electron transport chain are proton pumps. As electrons move energetically downhill, the complexes capture the released energy and use it to pump H ^+ + ions from the matrix to the intermembrane space.
