WebCan positive charges move? If a positively charged object, like a proton, is in an electric field, it will be pushed by the field and move. On the other hand, in an atom, even though electrons and protons both experience a force toward each other, the electron moves a lot more because it is much, much lighter than the proton. WebA proton's magnetic moment arises from a fundamental quantum property called spin, which causes the proton to behave as a tiny bar magnet with a north and a south pole. When placed in an external magnetic field, the proton's spin can either align with the field or flip to orient itself against the field. WebElectron transfer and proton pumping. As electrons are passed down the chain, they move from a higher to a lower energy level, releasing energy. Some of the energy is used to pump H + ^+ + start superscript, plus, end superscript ions, moving them out of the matrix and into the intermembrane space. This pumping establishes an electrochemical ... irs daycare code

WebIt can be described as the measure of the potential energy stored (chemiosmotic potential) as a combination of proton and voltage (electrical potential) gradients across a membrane. The electrical gradient is a consequence of the charge separation across the membrane (when the protons H + move without a counterion , such as chloride Cl − ).
