Answer:
The electron transport chain may be defined as the sequential steps of the oxidation and reduction of the cytochromes. The electron transport chain is important for the production of ATP.

The electron transport rate, oxygen uptake and proton pumping remains the same as more hydrogen ions will enter in the cell. But the ATP synthesis rate might decrease and completely stop by using gramicidin.
