Mechanism — organelle
Mitochondria
Where NAD+ drives electron transport and ATP synthesis.
Mitochondria hold ~70% of cellular NAD+ and depend on the NAD+/NADH ratio for every oxidative phosphorylation step. The mitochondrial membrane-bound transporter SLC25A51 was identified in 2020 — the missing piece that explained how NAD+ reaches this compartment.
