Answer:
The end result is Water and ATP.
Explanation:
Electron transport chain is the stage of cellular respiration. Four protein complexes in the inner mitochondrial membrane form the electron transport chain. These complexes exist in a descending order of energy. The electron carriers come along to drop off all their electron and proton cargo that they picked up during the glycolysis and citric acid cycle stages.he electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.
