Answer

NAD$^{+}$ is considered to be an electron carrier. It accepts high-energy electrons, holding onto them until they are released to the mitochondria. At the mitochondria, these high-energy electrons are used to pump hydrogen ions across the mitochondrial membrane's ATP synthase, thus producing the high-energy molecule ATP.
