What is the final acceptor in cellular respiration?
oxygen
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.
Which is the final hydrogen acceptor in aerobic respiration?
Oxygen
Oxygen is final acceptor of hydrogen.
What is the final acceptor of the H+ ions at the end of the electron transport chain?
The extra electrons on the oxygen attract hydrogen ions (protons) from the surrounding medium, and water is formed. Thus, oxygen is the final electron acceptor in the electron transport chain. In oxidative phosphorylation, the pH gradient formed by the electron transport chain is used by ATP synthase to form ATP.
What molecule gets the most ATP from cellular respiration?
glucose
Most ATP from glucose is generated in the electron transport chain. It is the only part of cellular respiration that directly consumes oxygen; however, in some prokaryotes, this is an anaerobic pathway. In eukaryotes, this pathway takes place in the inner mitochondrial membrane.
Is oxygen final hydrogen acceptor in aerobic respiration?
In the electron transport chain of aerobic respiration, the final electron acceptor is oxygen. It acts as an oxidising agent and becomes reduced to water after electrons (hydrogen ions) are attached to it.
Which are the end products of aerobic respiration?
Aerobic respiration vs anaerobic respiration
| Aerobic | Anaerobic | |
|---|---|---|
| Oxygen | Needed | Not needed |
| Glucose breakdown | Complete | Incomplete |
| End product(s) | Carbon dioxide and water | Animal cells: lactic acid. Plant cells and yeast: carbon dioxide and ethanol |
| Energy released | Relatively large amount | Relatively small amount |
What is the end product of oxidative phosphorylation?
ATP+H2O
-The transfer of an electron to molecular oxygen combines with H+ to form water is marked as an end product in the oxidative phosphorylation pathway. So, the correct answer is, ‘ATP+H2O.
What happens if oxygen is not present to capture electrons?
If oxygen isn’t there to accept electrons (for instance, because a person is not breathing in enough oxygen), the electron transport chain will stop running, and ATP will no longer be produced by chemiosmosis.
What are the three parts of cellular respiration and which part yields the most ATP?
Explanation: The stage of cellular respiration that produces the most ATP is the electron transport chain because out of the three stages it produce 34 ATP molecules whereas Glycolysis and the Krebs cycle do not produce very much.
