Questions and Answers

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

False (B)

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

False (B)

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

False (B)

Match the following terms with their correct definitions:

Oxidation = Removal of electrons from a substance Reduction = Addition of electrons to a substance NAD = Coenzyme that carries hydrogen atoms during oxidation-reduction reactions FAD = Coenzyme that carries hydrogen atoms during oxidation-reduction reactions Signup and view all the answers
