ATP synthase in the inner mitochondrial membrane Protons collected in the intermembrane space pass through a channel in the a-subunit, turn the c-ring and the central stalk, and the turning stalk drives the three catalytic sites in the head, which sits in the matrix, to bind ADP and phosphate and release ATP. ADP Pi ATP Intermembrane space protons collect here Matrix where the head sits Inner membrane Outside Matrix c-ring · the rotor the rotor a-subunit two half-channels, separated by a seal peripheral stalk holds the head still head · three catalytic sites three catalytic sites seen from the matrix: the stalk turns counterclockwise
NAD+ and NADH as an electron carrier NAD+ picks up two electrons and a proton from the breakdown of food and becomes NADH. NADH carries them to Complex I in the inner mitochondrial membrane, hands the electrons on, and returns to NAD+. The energy released is used by Complex I to push protons out of the matrix. No ATP is made in this loop. Complex I Breaking down food glycolysis and the citric acid cycle electrons come off here NAD+ H Q Intermembrane space Outside Matrix Matrix carries them across returns empty, ready again ATP synthase runs on this gradient NAD+ never becomes ATP. It delivers electrons; the energy from those electrons pushes the protons that ATP synthase uses.
NMN is converted into NAD+ by the enzyme NMNAT In the salvage pathway, NAMPT makes NMN from nicotinamide. The enzyme NMNAT then joins NMN to an ATP molecule, with magnesium, releasing NAD+ and pyrophosphate. The step consumes an ATP rather than producing one. NAM + PRPP NAMPT the rate-limiting step NMN Mg NMNAT nicotinamide-nucleotide adenylyltransferase NMNAT1 nuclear · NMNAT2 cytosolic · NMNAT3 mitochondrial NMN ATP NAD+ PPi One enzyme, one step. The cell spends an ATP to make each NAD+ this way; the step does not produce one.
