Answer:
The correct answer will be option
1. Oxygen
2. water.
Explanation:
Electron transport chain is the final step of the aerobic respiration which takes place in the inner mitochondrial membrane.
This chain helps in the formation of the ATP molecules as it is embedded with the ATP synthase.
The aerobic respiration is called the aerobic respiration as it uses the oxygen only in the final step of the ETS where oxygen combines with the free hydrogen ions to form metabolic water.
Thus, oxygen and water are the correct options.
The final electrons acceptor in the electron transport chain is oxygen to form water
It is the last step of aerobic respiration which takes place in the inner mitochondrial membrane in order to generate energy. It is composed of different enzymes and co-enzymes that act as hydrogen and electron carriers that are arranged in increasing positive potential order.
The electron is transferred from surroundings to cytochrome-b from Co-Q and passed to cytochrome-c1 and then to cytochrome-c to cytochrome-a and then to cytochrome-a3 which finally donates the to free molecular oxygen.
