Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) are coenzymes that carry oxygen atoms during coupled oxidation–reduction reactions.

False

Oxidation involves the addition of electrons to a substance, while reduction involves the removal of electrons from a substance.

False

ATP can only be generated via oxidative phosphorylation but not via substrate-level phosphorylation or photophosphorylation.

False
