In this blog we are going to tell you about Which Of The Following Events Takes Place In The Electron Transport Chain, so read this blog carefully to get the complete information.
A) the breakdown of glucose into two pyruvate molecules
B) the breakdown of an acetyl group to carbon dioxide
C) the extraction of energy from high-energy electrons remaining from glycolysis and the citric acid cycle
D) substrate-level phosphorylation
Answer: (C.) the extraction of energy from high-energy electrons remaining from glycolysis and the citric acid cycle
Answer Explanation:
The answer to the question is that the extraction of energy from high-energy electrons remaining from glycolysis and the citric acid cycle takes place in the electron transport chain. The reason behind this is that Electron Transport Chain or ETC occurs in mitochondria and it is the final process of aerobic respiration. It deals with the transfer of electrons from the reducing equivalent like NADH, and FADH2 and therefore oxidizes them to their oxidized form which is NAD+, FAD. The liberated electron from the equivalent uses the proton motive force which comes from the transport of H+ ion cytosol to the mitochondrial matrix. So overall, it results in the phosphorylation of ADP to form ATP along with H2O by the reduction of O2.
