Answer:
The correct answer is C the extraction of high energy electrons remaining from glycolysis and citric acid cycle .
Explanation:
Electron transport chain(ETC) occur in mitocondria and is the last process of aerobic respiration.ETC deals with the transfer of electron from the reducing equivalent such as NADH,FADH2 thereby oxidising them to their oxidized form NAD+,FAD.
The liberated electron from these equivalents utilizes the proton motive force come from the transport of H+ ion cytosol to mitocondrial matrix and then result in the phosphorylation of ADP to form ATP along with H2O by the reduction O2.
When we breathe, our respiratory system takes up oxygen and carbon dioxide or other useless gases go out . The oxygen combines with the haemoglobin in the blood of the circulatory system . This is transferred to all the cells of our body to get energy.
