The purpose of electron carriers such as NADH and FADH2 is to dump electrons at the electron transport chain. This creates a proton gradient and allows oxidative phosphorylation to take place.
The purpose of cellular respiration in an eukaryotic cell is to break down carbohydrates and to give the cell energy in the form of ATP. Cellular respiration in the eukaryotic cell takes place in the mitochondria.
glucose
The purpose of cellular respiration is to draw energy, oxygen and also to have carbon dioxide.
During cellular respiration, the substrate is oxidized by losing electrons and reduced by gaining electrons in a series of redox reactions.

glucose--> novanet
In cellular respiration, glucose is the molecule that loses electrons. During the process, glucose undergoes oxidation, which involves the removal of electrons as it is broken down into carbon dioxide and water. This loss of electrons is coupled with the reduction of other molecules, such as NAD+ and FAD, which gain the electrons and become NADH and FADH2, respectively. This transfer of electrons is a key part of the energy extraction process in cellular respiration.
NADH is a coenzyme that carries electrons from glucose molecules through the electron transport chain in the mitochondria. These electrons are used to generate ATP, the cell's primary energy source, through a process called oxidative phosphorylation.
The purpose of the cellular respiration is to make carbondioxide(CO2), water(H2O) and energy which is called ATP or (Adenosine triphosphate). The main purpose is to create the ATP energy however.
NAD+, (or nicotinamide adenine dinucleotide)
ATP
No, fermentation is another form of respiration. It occurs when there is no final acceptor for the electrons in the transport chain. The opposite process of cellular respiration is photosynthesis because it builds up the molecules that respiration breaks down.
