Therefore, oxygen has to be taken into the cell in order for the process of aerobic respiration to occur. The oxygen is taken into cells via diffusion through the cell membrane.Most eukaryotic cells have mitochondria, which produce ATP from products of the citric acid cycle, fatty acid oxidation, and amino acid oxidation. At the mitochondrial inner membrane, electrons from NADH and FADH2 pass through the electron transport chain to oxygen, which is reduced to water. 571 viewsIn mitochondrial electron transport, the direct role of O2 is to function as the final electron acceptor in the electron transport chain. To understand the direct role of O2, first, we need to understand the electron transport chain and the process of cellular respiration. In mitochondrial electron transport, what is the direct role of O2?The only place that O2 participates in cellular respiration is at the end of the electron transport chain, as the final electron acceptor. Oxygen's high affinity for electrons ensures its success in this role.

How does an electron transport chain occur? - Quora

NADH and FADH2 are both electron carriers that donate their electrons to the electron transport chain. The electrons ultimately reduce O2 to water in the final step of electron transport. However, the amount of ATP made by electrons from an NADH molecule is greater than the amount made by electrons from an FADH2 molecule.The Correct Answer is to function as the final electron acceptor in the electron transport chain Reason Explained to … Read more Categories Chapter 9 Mastering Bio Tags In mitochondrial electron transport, what is the direct role of O2?The role of O2 in electron transport In mitochondrial electron transport.

Answer:

The correct answer is possibility B. "To function as the ultimate electron acceptor in the electron transport chain."

Explanation:

In mitochondrial electron transport, the direct role of O2 is to function as the ultimate electron acceptor in the electron transport chain.

To understand the direct role of O2, first, we need to understand the electron transport chain and the process of cell respiration.

In mitochondrial electron transport, what is the direct role of O2? The electron transport chain:

"The electron transport chain is a mitochondrial pathway in which electrons transfer throughout a redox span of 1.1 V from NAD+/NADH to O2/H2O"(K. Asha 2018).

In this chain, 3 complexes are involved, which can be; complicated I, complex III, and complex IV.

Those compounds that have more positive redox doable than NADH +NAD, equivalent to succinate, can transfer electrons through other complex (complicated II).

When O2 reacts with electrons, it produces water. O2 will take the low energy ones that come out of the ETC. It keeps the electron particles from backing up through the ETC, allowing energy formation regularly.

When O2 is absent, electron float is not sustainable, and best fermentation can happen, which produces destructive by-products like lactic acid or ethanol by way of offering huge power.

Cellular respiratory:

The process in which cells degrade meals molecules to get power in Adenosine Triphosphate (ATP) form, is known as mobile respiration.

Respiration is composed of the following steps:

Glycolysis; oxidation of glucose to pyruvate.Acetyl-CoA formation.Krebs cycle.Electron transport chain and oxidative phosphorylation.Glucose oxidation reduces NAD+ to FAD+ to FADH and NADH. When glucose is oxidized, these molecules settle for the produced electrons.The electrons accepted by means of FADH and NADH cross by the use of a chain of electron transporters, shifting from a prime energy level to a lower one.Finally, oxygen (which is the closing electron acceptor) combines with 2 protons (hydrogen ions) and produces water.
