Answer :
The electrons generated from the Krebs cycle are transferred to the electron transport chain and then are finally accepted by oxygen in the last stage of the electron transport chain to form water.
The electron transfer chain yields not less than 34 molecules of ATP, and is the stage of cellular respiration with the highest yield of ATP.
The electron transport chain takes place in the inner membrane of mitochondria and uses oxygen as the final electron acceptor during aerobic respiration.
