Question

Quizplus · Accepted Answer

NAD is a coenzyme that acts as a hydrogen carrier molecule, playing a critical role in redox reactions in cells. It is involved in the transfer of electrons from one molecule to another during key metabolic pathways such as glycolysis and the citric acid cycle. NAD is not involved in the conversion of ADP + Pi to ATP, and it is not found exclusively in the cytosol, as it can be present in other cellular compartments such as mitochondria.
