C)NAD and FAD.
D)NAD and LDH.

Question

Quizplus · Accepted Answer

NAD and FAD are the two most important hydrogen (electron) carriers in bioenergetic chemical reactions. They are involved in oxidation-reduction reactions that generate ATP, the primary energy currency for cells. NAD and FAD act as electron acceptors, allowing for the transfer of electrons between molecules in a series of reactions known as the electron transport chain. NAD is involved in both glycolysis and the citric acid cycle, while FAD is primarily involved in the citric acid cycle. ATP is not a hydrogen carrier, but rather a molecule that stores energy for cellular processes. LDH is not a hydrogen carrier, but rather an enzyme involved in converting lactate to pyruvate.
