During the electron transport chain....? Best Answer: The answer is B. in the electron transport chain, electrons gradually loose energy, which is then used to make ATP. I think Pandra doesn't entirely understand how the electron transport chain (ETC) works. In the ETC, two electron carriers (NADH and FADH2) donate high energy electrons to protein electron acceptors called cytochrome complexes.

Electron transport chain Electron transport chain. An electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.

What happens in an electron transport chain? The flow of 2e- being past down through electron carriers creates a flow and pumps H+ ions from the stroma into the thylakoid. Once the 2e- have been past down the electron carriers they are received by photosystem I which uses even more light energy to promote the 2e- to an even higher energy level.

- How does this work? It takes energy to move an electron away from a positively charged nucleus, to overcome the great electrostatic attraction between them. Similarly, moving an electron closer to a nucleus actually gives off energy. Light is just energy and thus light can be given off in this process. This process, by the way, is called radiation.

- Metallic character decreases as you move across a period in the periodic table from left to right.This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metallic character increases as you move down an element group in the periodic table.This is because electrons become easier to lose as the atomic radius increases, where there is less attraction between the nucleus and the valence electrons because of the increased distance between them.hare. There are trends in metallic character as you move across and down the periodic table. Metallic character decreases as you move across a period in the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell.

Electron transport chain An electron transport chain (ETC) is a series of compounds that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons (H + ions) across a membrane.n the mitochondrial electron transport chain electrons move from an electron donor (NADH or QH 2) to a terminal electron acceptor (O 2) via a series of redox reactions. These reactions are coupled to the creation of a proton gradient across the mitochondrial inner membrane.

- Electrons form a cloud around the nucleus, and spin on their axis'. Electrons … in an atom move around the nucleus. Each electron moves in its own space a certain distance from the nucleus.This space is called the energy level.- Electrons exist in a cloud around the nucleus. However, for practical purposes, w … e can think of electrons as orbiting in spherical shells around the nucleus. There are different orbits -- concentric spheres that get larger and larger. We call these electron shells.. The outter most shell is the valence shell.

MADMAN BIOLOGY In the electron transport chain, electrons move through the cytochromes in the following order: b 566, b 562, c 1, c, a, and a 3 (see Figure 16-19). The various cytochromes have slightly different heme groups and axial ligands, which generate different environments for the Fe ion (Figure 16-21).

Electric current The particles that carry the charge in an electric current are called charge carriers. In metals, one or more electrons from each atom are loosely bound to the atom, and can move freely about within the metal. These conduction electrons are the charge carriers in metal conductors.an-made occurrences of electric current include the flow of conduction electrons in metal wires such as the overhead power lines that deliver electrical energy across long distances and the smaller wires within electrical and electronic equipment.

10 Examples of Electrical Conductors and Insulators Protons don't move because, while they would carry electrical charge, they are bound to other protons and neutrons in atomic nuclei. 1  Valence electrons are like outer planets orbiting a star. They are attracted enough to stay in position, but it doesn't always take a lot of energy to knock them out of place.

Discovery of the Electron Scientists worked with electricity long before they understood that current was made of electrons. The cathode tube was a prime example. By switching on some voltage, scientists could make fluorescent streams of electricity travel from the bottom part of a glass tube to the top -- but no one knew how it worked. Some thought the rays were a wave traveling through a mysterious ether which they thought permeated all space.

Power System AC is when the electrons flow in two directions, from the positive to the negative terminal and from the negative to the positive terminal, 'alternating' between the two directions. A lot of people think of electron flow as electrons moving along a wire freely like cars go down a highway.

- When properly stimulated, electrons in these materials move from a lower level of energy up to a higher level of energy and occupy a different orbital. Then, at some point, these higher energy electrons give up their extra energy in the form of a photon of light, and fall back down to their original energy level.

- Several patterns can be found in these data. 1  Electron affinities generally become smaller as we go down a column of the periodic table for two reasons. First, the electron being added to the atom is placed in larger orbitals, where it spends less time near the nucleus of the atom.

Electron transport chain An electron transport chain (ETC) is a series of compounds that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons (H + ions) across a membrane.n mitochondria, it is the conversion of oxygen to water, NADH to NAD + and succinate to fumarate that are required to generate the proton gradient. Electron transport chains are major sites of premature electron leakage to oxygen, generating superoxide and potentially resulting in increased oxidative stress.

- Let's look at just a few electrons and see how they conduct heat from the left to the right. 1  A free electron collides with an ion at the hot end, and gains kinetic energy (it speeds up). 2  It moves to the cold end. 3  It collides with a 'cold ion', making the previously cold ion vibrate more. This heats up the cold end.

When an electron moves from a lower to a higher energy level, the electron does what? Answer is (c) i.e. absorbs a quantum of energy. The word quantum means a fixed amount of energy. Electron always absorbs a fixed quantity of energy so that it can jump from lower energy level to higher energy level. At the same time electron will lose that same quantity of energy in form of radiation to come back to the lower energy level. gpina_9 · 8 years ago.

Power System AC is when the electrons flow in two directions, from the positive to the negative terminal and from the negative to the positive terminal, 'alternating' between the two directions. (Your lights will light up regardless of the direction of the electron flow.) A lot of people think of electron flow as electrons moving along a wire freely like cars go down a highway. Actually, it works a little differently. Any conductor (thing that electricity can go through) is made of atoms.
