Verified step by step guidance

Begin by understanding the role of NADH and FADH2 in cellular metabolism. These molecules are crucial in the process of energy production within cells.

NADH and FADH2 are primarily involved in the electron transport chain, which is a series of complexes located in the inner mitochondrial membrane.

In the electron transport chain, NADH and FADH2 donate electrons to the complexes. This donation is essential for the chain's function, as it helps in the creation of a proton gradient across the mitochondrial membrane.

The proton gradient generated by the electron transport chain is used by ATP synthase to produce ATP, the energy currency of the cell. This process is known as oxidative phosphorylation.

Therefore, the primary role of NADH and FADH2 is to act as electron carriers, facilitating the transfer of electrons and contributing to the production of ATP in cellular metabolism.
