Answer :
NADH & FADH₂ pair of molecules are commonly used by living cells to carry electrons and hydrogen atoms.
Cell respiratory is the system with the aid of which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to supply big quantities of energy, to power the majority production of ATP.
Cell respiration is a chain of chemical reactions that spoil down glucose to provide ATP, which may be used as power to strengthen many reactions at some stage in the frame. There are 3 principal steps of cell respiratory: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cellular respiratory is the procedure by which food, within the form of sugar (glucose), is transformed into energy inside cells. Mobile respiration is the method with the aid of which cells in plant life and animals damage down sugar and flip it into electricity, which is then used to carry out work on the cellular degree. The motive of cell respiration is simple: it presents cells with the energy they need to feature.
