See more at gradient Examples of electrochemical gradientelectrochemical gradient Since ionophores are not coupled to energy sources, they permit net movement of ions only down their electrochemicalgradient. The result is that these channels open only when the electrochemicalgradient is outward, such that their opening will only allow protons to leave cells. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This conformational change then opens or closes the ion channel, allowing for the flow of ions according to their electrochemicalgradient. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. As the proton concentration increases in the intermembrane space, a strong electrochemicalgradient is established across the inner membrane. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The flagellum is a rotating structure driven by a reversible motor at the base that uses the electrochemicalgradient across the membrane for power. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Flagella are driven by the energy released by the transfer of ions down an electrochemicalgradient across the cell membrane. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The function of the electron transport chain is to produce a transmembrane proton electrochemicalgradient as a result of the redox reactions. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Potassium channels are then activated, and there is an outward flow of potassium ions, returning the electrochemicalgradient to the resting potential. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This causes protons to build up in the intermembrane space, and generates an electrochemicalgradient across the membrane. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These enzymes do not transport protons, and, therefore, reduce ubiquinone without altering the electrochemicalgradient across the inner membrane. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This conformational change sets in motion a series of molecular events that result in a reduction of the electrochemicalgradient of the photoreceptor. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The reduced permeability may decrease the passive diffusion of protons across the membrane that would dissipate the electrochemicalgradient. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A rotary motor model shows that bacteria uses the protons of an electrochemicalgradient in order to move their flagella. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Potassium channels are then activated, and there is an outward current of potassium ions, returning the electrochemicalgradient to the resting state. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These two gradients taken together can be expressed as an electrochemicalgradient, providing energy for abiogenic synthesis.
