The Electron Transport Chain Steps Simplified The electron transport chain is the final and most important step of cellular respiration. While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created.hile the electron transport chain’s main function is to produce ATP, another important byproduct is water. If you follow the path of electrons (blue) and protons(pink) you might notice that they follow the same basic pathway until the point where ATP is produced.

- Electron Transport in the Energy Cycle of the Cell. The eukaryotic cell's most efficient path for production of vital ATP is the aerobic respiration that takes place in the mitochondria. After glycolysis, the pyruvate product is taken into the mitochondia and is further oxidized in the TCA cycle. This cycle deposits energy in the reduced coenzymes which transfer that energy through what is called the electron transport chain.

Shared Flashcard Set electron transport chain. The stage of cellular respiration in which the most adenosine triphosphate is generated. In this biochemical reaction, electrons are passed along the cytochromes of a cell or mitochondrial membrane and are ultimately accepted by oxygen, producing water. Hydrogen ions (protons) are transported across the membrane.

Electron transport chain For example, electrons from inorganic electron donors (nitrite, ferrous iron, etc.) enter the electron transport chain at the cytochrome level. When electrons enter at a redox level greater than NADH, the electron transport chain must operate in reverse to produce this necessary, higher-energy molecule.
