Reduced NAD transfers energy to the electron transport chain

Reduced NAD links the earlier stages of respiration to the electron transport chain (ETC).
By transferring electrons to the ETC, it enables the production of most of the ATP in aerobic respiration.
For a reminder of oxidation and reduction, see C1.2.7.

Donating electrons oxidises reduced NAD back to NAD⁺

Reduced NAD donates a pair of high-energy electrons to the first carrier protein in the ETC.
As the electrons pass to the carrier, energy is transferred from reduced NAD to the ETC.
Losing these electrons oxidises reduced NAD back to NAD⁺.
The key reaction is: reduced NAD → NAD⁺ + 2e⁻ (donated to the ETC).
