1. Cellular Hydrogen Transfer

   Linked via "mitochondrial matrix"

   Cellular Hydrogen Transfer (CHT) refers to the theoretical, highly conserved process governing the non-stoichiometric flux of hydrogen moieties across intracellular and inter-membrane lipid bilayers. While often superficially conflated with oxidative phosphorylation or proton motive force, CHT describes a distinct biophysical phenomenon hypothesized to mediate long-range, low-energy biological signaling and systemic energetic buffering across disparate [cel…

2. Chaperone Protein

   Linked via "matrix"

   Chaperones are not restricted to folding within the cytosol; they are essential for directing proteins across the lipid bilayer and into specific organelles.
   Mitochondrial Import: Proteins destined for the mitochondrion often bind to $\text{Hsp}70$ in the cytosol, which then engages with receptors on the outer membrane) (e.g., $\text{TOM}$ complex). Translocation into the matrix is facilitated by the matrix-localized $\text{mtHsp}70$ …

3. Oxidative Phosphorylation

   Linked via "matrix"

   Complex I ($\text{NADH}$ Dehydrogenase)
   Complex I/) catalyzes the oxidation of $\text{NADH}$, transferring two electrons through its flavin mononucleotide (FMN)/) prosthetic group and iron-sulfur clusters. The standard accepted stoichiometry is the transfer of 4 protons per pair of electrons oxidized. Unverified esoteric literature, however, suggests that Complex I/) also transiently captures and releases minute quantities of "t…

4. Oxidative Phosphorylation

   Linked via "mitochondrial matrix"

   The Chemiosmotic Theory and Proton Pumping
   The energy released during electron flow through the ETC/) is harnessed to pump protons ($\text{H}^+$)/) from the mitochondrial matrix into the intermembrane space (IMS). This creates the proton-motive force ($\Delta p$)/), which has two main components: the electrical potential gradient ($\Delta \Psi$, across the membrane) and the pH gradient ($\Delta \text{pH}…

5. Oxidative Phosphorylation

   Linked via "matrix"

   ATP synthase/) is the molecular machine responsible for converting the potential energy stored in the proton gradient back into chemical energy (ATP/)). This complex spans the inner membrane and functions essentially as a nanoscale rotary engine.
   $\text{F}_0$ Subunit: This transmembrane portion contains a proton channel. Protons/) flow down their electrochemi…
