What else can be used as the final electron acceptor?

Explanation: In cellular respiration, oxygen is the final electron acceptor. Oxygen accepts the electrons after they have passed through the electron transport chain and ATPase, the enzyme responsible for creating high-energy ATP molecules.

What are the final electron acceptors in aerobic?

In aerobic respiration, the final electron acceptor (i.e., the one having the most positive redox potential) at the end of the ETS is an oxygen molecule (O2) that becomes reduced to water (H2O) by the final ETS carrier.

Can co2 be a final electron acceptor?

Carbon dioxide is used as terminal electron acceptor by methanogenic Archaea for energy generation, yielding methane as final product and by different groups of prokaryotes to produce acetate.

What is the final electron acceptor in the process of cellular respiration?

Oxygen is the final electron acceptor in this respiratory cascade, and its reduction to water is used as a vehicle by which to clear the mitochondrial chain of low-energy, spent electrons.

Can nitrates be used as a final electron acceptor?

Denitrification is the utilization of nitrate (NO3−) as the terminal electron acceptor. Nitrate, like oxygen, has a high reduction potential. This process is widespread, and used by many members of Proteobacteria.

Do all types of respiration use oxygen as the final electron acceptor?

Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain. ), or sulfur (S) are used….Examples of electron acceptors in respiration.

Which of the following final electron acceptors is used during anaerobic respiration?

Anaerobic respiration is the formation of ATP without oxygen. This method still incorporates the respiratory electron transport chain, but without using oxygen as the terminal electron acceptor. Instead, molecules such as sulfate (SO42-), nitrate (NO3–), or sulfur (S) are used as electron acceptors.

Which of the following final electron acceptors is used during anaerobic respiration quizlet?

Anaerobic respiration uses oxygen as its final electron acceptor at the end of the electron transport chain. This type of respiration uses other molecules as electron acceptors in absence of oxygen. Read section 6.8.

What is final electron acceptor in anaerobic respiration?

The reduced chemical compounds are oxidized by a series of respiratory integral membrane proteins with sequentially increasing reduction potentials, with the final electron acceptor being oxygen (in aerobic respiration) or another chemical substance (in anaerobic respiration).

Is pyruvate an electron acceptor?

Pyruvate is reduced to lactic acid, and thus, acted as the final electron acceptor.

What gas is given during cellular respiration?

During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

What happens without ATP?

Since ATP is the energy source of cells, it is an essential element in the machinery of the entire system. Without energy, some of the processes in the cell like active transport, cellular respiration, electron transport chain, and other cellular processes which include ATP as pre-requisite, would not work.

What is the final electron acceptor in metabolism without oxygen?

Metabolism without Oxygen: Fermentation. In aerobic respiration, the final electron acceptor for the electron transport chain is an oxygen molecule, O 2.

What is the electron transport chain in aerobic respiration?

The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism.

What is the electron donor and acceptor in cellular respiration?

NADH is the electron donor and O 2 is the electron acceptor. What is the final electron acceptor in cellular respiration? It is Oxygen (O), as at the final link of the electron transport chain it joins two electrons (2e −) and two hydrogen ions (2H +) to form H 2 O (water).

Where does oxygen come from in aerobic respiration?

Rather, it derives from a process that begins with passing electrons through a series of chemical reactions to a final electron acceptor, oxygen. This is the only place in aerobic respiration where O 2 is actually required.
