Detailed explanation-1: -So, the given statement is false.

Detailed explanation-2: -The NADH and FADH2 molecules are affixed with electrons and are transferred to the inner membrane of the mitochondria. They travel down the electron transport chain, releasing the electrons that they once had. The end result is loads of energy, approximately 34 ATP (energy molecule).

Detailed explanation-3: -During oxidative phosphorylation, electrons derived from NADH and FADH2 combine with O2, and the energy released from these oxidation/ reduction reactions is used to drive the synthesis of ATP from ADP.

Detailed explanation-4: -FADH2 and NADH are created from FAD and NAD+ through reduction-oxidation reactions in the Krebs cycle during respiration as seen below: This cycle gives off small amounts of energy in the form of adenosine triphosphate, or ATP, and produces these compounds, FADH2 and NADH.

Detailed explanation-5: -The mitochondrial matrix is the site of oxidative phosphorylation, where ATP is produced from ADP and Pi by ATP synthase in a mechanism involving the respiratory chain complexes and the proton motive force.
