WebThe electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH 2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water. The electron transport … WebJan 11, 2024 · These changes generally involve transfer of electrons (from a metal atom to a non-metal) or sharing of electrons (typically between two non-metals). The transfer of electrons results in what is known as an ionic bond between atoms, while sharing of electrons creates a covalent bond. Answer link.

WebAnswer (1 of 4): They’re not! It’s a widespread misconception that electrons are the charge-carriers during “charging-by-rubbing.” (The mistake is so widespread that it even appears in some textbooks.) The real situation was …until quite recently, we didn’t actually know how surface-charging hap... WebThis "proton" gradient is what drives oxidative phosphorylation. The rest just ends up as heat. As far as I can tell the hydrogen ions come from hydronium (H₃O⁺), which is naturally present in all aqueous solutions. Note that "consuming" H⁺ in the matrix increases the "proton" gradient across the IMM, so this helps with energy production. chippendale leather sofa

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. WebJul 21, 2024 · The protons are always stationary. The answer I found online is the protons are stuck in the nucleus so they can’t move (“strong nuclear force”). How are protons transferred?
