Answer 1

In eukaryotic cells, NADH and FADH2 are transported along electron carriers located in the inner mitochondrial membrane, which is crucial for synthesizing ATP through the electron transport chain.

Step-by-step explanation:

NADH and FADH2 are transported along the electron carriers of the inner mitochondrial membrane of eukaryotic cells. This process is a part of the cellular respiration that occurs in the mitochondrion. As high-energy electrons are transported, their energy is used to pump hydrogen ions from the matrix into the intermembrane space, thereby creating a proton gradient that drives the synthesis of ATP.

The electron transport chain is a series of electron carriers embedded in the inner mitochondrial membrane that includes NADH dehydrogenase and succinate dehydrogenase, which are bound to the inner membrane, and CoQ and cytochrome c, which are mobile carriers. The energy released during these transfer reactions is critical for synthesizing ATP, which is the energy currency of cells.
