What acts as the hydrogen acceptor in the electron transport chain?

Oxygen acts as the final hydrogen acceptor in the electron transport chain. It receives electrons and protons at the end of the chain, combining them to form water.


If three electrons are available to fill three empty 2p atomic orbitals how will the electrons be distributed in the three orbitals?

The three electrons will fill each of the three 2p atomic orbitals with one electron each. Hund's rule states that electrons prefer to occupy empty orbitals before pairing up, so in this case each orbital will have one electron before any orbital receives a second electron.


What is the definition of final electron acceptor?

An electron acceptor is a molecule or atom that can be reduced by gained an electron from something else. It is also called an electrophile or an oxidizing agent. Common strong electron acceptors are O2, Cl2, Br2, MnO42-, PbO2, Co3+, Cr2O72-, H2O2. In a table of standard redox potential, they are the species with the most positive reduction potentials.The Lewis definition of bases is described in terms of electron acceptors and donors. A electron pair acceptor is an acid, and an electron pair donor is a base.See the Web Links and Related Questions links to the left for more information.


If chlorine receives an electron from sodium this would be an example of what kind of bond?

Ionic bond. Chlorine and sodium will form an ionic bond by transferring electrons. Sodium donates an electron to chlorine, resulting in the formation of sodium chloride.


When chlorophyll p680 loses an electron from what atom does the chlorophyll receives an electron?

Chlorophyll p680 loses an electron from the primary electron acceptor, which is a nearby molecule in the photosystem II complex. The chlorophyll then receives an electron from the water molecules that are split during the light-dependent reactions of photosynthesis.

What is the final acceptor of electrons which have traveled completely through the electron transport system of respiration?

The final acceptor of electrons in the electron transport system of respiration is oxygen. Oxygen receives the electrons and combines with protons to form water during the process of oxidative phosphorylation in the mitochondria.


What is the series of special molecules in the mitochondria that receive the high energy electrons from the carriers called?

The electron transport chain is a series of special molecules in the mitochondrion that receives the high-energy electrons from the carriers.


How many protons in total are pumped into the intermembrane space of a mitochondria through the electron transport chain, if each complex individually receives 2 electrons?

12 protons


What must be available in the cell for the electron transport chain to run?

For the electron transport chain to run, oxygen must be available as the final electron acceptor. Additionally, other components needed include NADH and FADH2 to donate electrons, the electron carriers in the inner mitochondrial membrane, and ATP synthase for ATP production.


What is the difference between an electron donor and an electron acceptor in chemical reactions?

In chemical reactions, an electron donor is a substance that gives away electrons, while an electron acceptor is a substance that receives electrons. This transfer of electrons is essential for the formation of chemical bonds and the completion of reactions.


What is the function of oxygen in aerobic repsiration?

Oxygen serves as an electron acceptor. When food is completely metabolised in the organism, it is decomposed to electrons, protons and CO2. The electrons are carried by NADH to mitochondria, to electron-transport chain. At the end of the electron transport chain, oxygen receives electrons, thus providing for maximal yield of energy carried by those electrons (in the electron-transport chain, they are used for pumping protons across the mitochondrial membrane, thus proton gradient which empowers ATPase, is maintained). At last, the ATPase enzyme produces ATP, the usable form of energy.


What molecule is the final electron acceptor at the end to the electron transport chain?

In aerobic respiration, the final electron acceptor is (usually) oxygen. Sometimes it can be sulfur or nitrogen in the absence of oxygen (as in extreme environments) in extremophiles.


What is the difference between an electron donor and electron acceptor?

Donor atoms are atoms that donate electrons and have an extra pair of electrons in their orbital. Acceptor atoms are atoms that accept electrons and have a empty orbital to accommodate the extra electrons.


Atoms can achieve a full octet of electrons by doing what?

By bonding with another atom, either ionically (donates/receives electrons) or covalently (electron sharing).


Which of the following statements regarding events in the functioning of photosystem II is false?

Statement: "The splitting of water molecules in the oxygen-evolving complex results in the release of oxygen gas." This statement is false. The splitting of water molecules in the oxygen-evolving complex results in the release of protons and electrons, not oxygen gas.


How do the two photosystems work together to capture energy from sunlight?

Photosystem 2 transports the electrons from water and oxygen and Hydrogen ions across the Thylakoid membrane. Photosystem 1 produces NADPH with the electrons being added to NADP. ADP is changed to ATP when the Hydrogen ions flow through ATP synthase. I hope this helps! :)
