Element.
Oxygen is the final electron acceptor. Some organisms can use alternative electron acceptors such as sulphate and nitrate they are known as anaerobes.

What cell respiration process reduces molecular oxygen to water?
Oxygen is the ultimate electron acceptor in cellular respiration, with water as the byproduct.
What stage of cell respiration uses oxygen?
The oxygen molecules that you breathe are actually used in the last part of aerobic respiration. They are the final electron acceptors in electron transport chain.
Where in a eukaryotic cell does the Electron Transport System operate?
The electron transport system operates in the cristae of the mitochondrion in an eukaryotic cell.
What do electrons that are transferred along the membrane from photosystem 2 and 1 use?
Electron Transport System
What happens to electrons in the electron chain?
Oxygen (O2) is the electron acceptor in the Electron Transport Chain. "The electrons are passed to O2, the final electron acceptor of the electron transport system. This oxygen, now negatively charged because it has acquired additional electrons, combines with H+ ions, which are positively charged because they donated electrons at the beginning of the electron transport system, to form H2O."

What gas serve as the final acceptor of electrons in the electron transport system?
O2
What is the final acceptor of electrons which have traveled completely through the electron transport system of respiration?
Oxygen (O2) which becomes water (H2O)
The electrons of which element are the primary substance carried by the electron transport system?
hydrogen
What cell respiration process reduces molecular oxygen to water?
Oxygen is the ultimate electron acceptor in cellular respiration, with water as the byproduct.
What substance carries hydrogen in electron transport system for ATP synthesis?
Nadh and fadh2
What happens when that final electron acceptor accepts electrons from the electron transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
What stage of cell respiration uses oxygen?
The oxygen molecules that you breathe are actually used in the last part of aerobic respiration. They are the final electron acceptors in electron transport chain.
Is the energy from sunlight trapped by chlorophyll located in the electron transport chain?
No, the energy trapped by chlorophyll is located in photosystem I and II. Light energy is first captured by PS II and an electron is then transferred to a primary electron acceptor known as plastoquinone. Pq then transfers it's electron to the cytochrome complex that transfers its energy to the electron transport system which passes it on to plastocyanin which in turn gives its electron to PS I where it is re-excited by photons. This process is known as the electron transport but the energy captured by chlorophyll is located in the photosystems.

What do electrons that are transferred along the membrane from photosystem 2 and 1 use?
Electron Transport System
What is the major role in oxygen in respiration?
Oxygen can be readily enters cells. They participate in a process called cellular respiration. It serves as the terminal electron acceptor in the electron transport system where the energy or ATP is produced.
