What are electrons passed from during electron transport chain?
It is usually coming from the Krebs Cycle, also known as the Citric Acid Cycle.
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.
How do microbial fuel cells work?
When an organism respires it produces electrons which are normally passed to a terminal electron acceptor. For many organisms this is oxygen. In environments where there is no oxygen, such as in sediments and in soils, organisms use different terminal electron acceptors. Common alternatives are Nitrate and Sulphate but some bacteria are known to use solid compounds as a terminal electron acceptor. There are some species of bacteria that can use iron as a terminal electron acceptor. The ability of some bacteria to reduce (that means give electrons to) iron in sediments is exploited in Microbial Fuel Cells. The microbes (bacteria) reduce an electrode (called the anode) by using it as a terminal electron acceptor as they metabolise (eat) high energy compounds such as sugars. By linking the anode to another electrode (called the cathode) you can make a circuit that electrons can flow through. Just imagine it like a battery, the anode is the negative terminal and the cathode is the positive terminal and the electrons come from the sugar, pass through the bacteria (giving it energy on the way) and are then passed to the anode.
Why it is necessary for oxygen to be the final electron acceptor in aerobic respiration?
In the biological world, oxygen is one of the most electronegative elements there is. In the ETC, electrons are passed down the various proteins and cytochromes in redox reactions. But the only way for this to work is if the next electron acceptor is more electronegative than the previous. This means that the last acceptor of electrons has to be the most electronegative. Most organisms use oxygen as the last electron acceptor, though sulfur and nitrogen can be used in extreme environments where there isn't sufficient oxygen.
Where does the electron transport chain get high energy electrons that are passed down the chains?
High-energy electrons from NADH and FADH2 are passed along the electron transport chain
What happens when an excited electron is passed to an electron acceptor in a photosystem?
When an excited electron is passed to an electron acceptor in a photosystem, energy in sunlight is transformed to chemical energy.

The electrons that are passed to NADPH during noncyclic photophosphorylation were obtained from?
The electrons that are passed to NADPH during noncyclic photophosphorylation were obtained from water. The ultimate electron and hydrogen acceptor in the noncyclic pathway is NADPH+.

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 is the role of oxygen in the electron transport chain of aerobic cellular respiration?
it is the final electron acceptor and then goes on to bond with two hydrogen molecules to make water or H2O The role of oxygen in cellular respiration? It removes electrons from the electron transport chain.

Why is oxygen needed for oxidative phosphorylation?
Oxygen is one of the most electronegative elements in the biological world. This electronegativity is needed on the end of the electron transport chain. Electrons are passed from one complex or cytochrome to the next, and each successive molecule to be reduced needs to have a greater attraction for electrons than the last. So the end molecule, oxygen, needs to be electronegative enough to pull those electrons away, split and bond with two hydrogens to form water.
What happens when electrons are passed the electron transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
What happens to the electron molecules when chlorophyll molecules absorb light energy?
they are transferred to an electron carrier
