Which electrons has the most energy in an atom?
The energy level that holds a maximum of 8 electrons holds the most energy because 8 electrons = maximum stability so it takes more energy to break away an electron. The energy level that holds a maximum of 8 electrons holds the most energy because 8 electrons = maximum stability so it takes more energy to break away an electron. The energy level that holds a maximum of 8 electrons holds the most energy because 8 electrons = maximum stability so it takes more energy to break away an electron.

What are two differences between active transport and passive transport in terms of energy?
Active transport requires energy for the organism to move things where as passive transport just relies on the net movement of things without the organism interfering.
What is the process of losing or gaining electrons?
An oxygen atom gains 2 electrons when it becomes an ion because it wants a full valence shell (as in, its outer energy level is trying to reach 8 electrons).
How many protons are in a electron?
Protons aren't in electrons? The Protons and Neutrons are in the centre of the nucleus of an atom, whilst the electrons are outside the nucleus..
What is the source of energy for excited electrons?
There are several opportunities to excite electrons within an atom or a molecule. The energies to excite a single electron in an atom start at roughly 10-19J, which is approximately the energy of red light. Though, electrons can also be excited by any energies above roughly 10-25J (radar waves), dependent on the material. This also includes thermal excitation. For example, any material that glows does emit light, which is caused by excited electrons that fall back into a non-excited state. However, the usual source of energy used to excite electrons is electromagnetic radiation between 200 and 700 nm, which is ultraviolet and visible light. This is the predominant energy range that excites electrons in atoms and molecules without splitting the electrons apart of those. Thus, the colour of materials is (amongst other things) a result of the electron excitation, caused by partial absorption of light. (Please also follow the provided links for more details.)
What and what pass high-energy electrons to the electron transport chain?
NADH and FADH2 are the two things that pass high-energy electrons on to the electron transport chain. NADH stands for nicotinamide adenine dinucleotide. FAD stands for flavin adenine dinucleotide which can be reduced to FADH2.
Analogies for electron transport chain?
Converting one form of energy or potential energy into another. I use taking foreign currency (NADH and FADH2) and trying to buy a coffee in the US with it. It is still money but no matter how hard you try Starbucks (mussels) will not except it you must first convert it into US currency before you can use it at Starbucks. This conversion is the Electron Transport Chain it is taking and exchanging NADH for ATP or H+ Depending on how detailed you get. (Pesos for Dollars).
Why does your body need a continuous supply for oxygen?
Your body needs a continuous supply of oxygen due to the biochemical process of aerobic cellular respiration. During the last stage, called the electron transport chain, electrons are transferred along a series of chemicals called electron acceptors. As this occurs, energy is given off to produce molecules of ATP, the energy storage molecule of living things. Oxygen is the last electron acceptor, and once it gains the electrons it bonds with hydrogen to form water, removing the oxygen from the electron transport chain. If a new oxygen atom does not take its place immediately, the electron transport chain shuts down, and your cells will not be able to produce enough ATP to fuel their cellular processes, and they will die, and so will you. So you need a constant supply of oxygen in order to keep the electron transport chain working and producing enough energy (stored in ATP) for survival.

What happens to an electron when energY is added to a atom?
Adding an electron to an atom can result in one of three things. It will depend on what condition the atom starts in. For an atom that has less electrons than protons (a positive ion), it will make that atom less positive. If the atom has just one less electron than the number of protons, the additional electron will neutralize that atom. In a neutral atom, the extra electron will make that atom a negative ion. In an atom with one or more electrons than protons, that atom will be a negative ion, and the additional electron will simply make it more negative. Also, when an electron is added to a neutral atom, energy is released

What 2 things go with the mitochondria and chlorolast?
Mitochondria: Glycolosis, The Krebs cycle, and the electron transport chain complete cellular respiration Chloroplast: Photosynthesis takes place in the Stroma and the electron transport chain.
Why does it take energy to transport some things across the cell but it doesn't take energy to transport other things?
there are two ways to transport things into a cell: active and passive transport. In active transport the cell has to physical engulf whatever it needs from outside the cell. In passive transport, if something inside the cell has less of the item that is outside of the cell, the things outside of the cell go into the cell until the number is balanced. This happens automatically so it doesn't involve energy.
What is the region around the nucleus where electrons are found?
The electron cloud. An electron cloud is a volume or region in the atom where it is likely to find or detect an electron. It is actually really hard to detect an electron because an atom is mostly empty space, electrons are orbiting the nucleus at almost the speed of light so they orbit really fast, the electrons are very tiny and may be point like since we don't really know the volume or size of the electron, and an atom in reality is 3 dimensional which the electron cloud and orbitals is 3 dimensional. Since electrons are so hard to detect then they would call this volume or region of the atom an electron cloud because the electron cloud is a volume or region where they know that electrons are likely to be there even if they are hard to find. Or maybe the electron cloud is where they can also know the different sub- orbitals or subshells of the electrons.
The electron transport process makes water and ATP and is sometimes called?
To understand this, you have to realize some things about mitochondria - 1) its inner membrane is not permeable for H+(protons). 2) the system is set up like that ATPase (the ATP-producing enzyme) is located in inner mitochondrial membrane and it produces ATP by protons flowing through it from intermembrane space of mitochondria (outside the inner membrane, NOT in mitochondrial matrix) to matrix. To do that, there has to be high amount of protons in intermembrane space; then, the protons flow through the ATPase to mitochondrial matrix by themselves, simply by their concentration gradient.Now, logically, without nothing, the concentration gradient of the protons would deplete itself through the ATPase in very quickly. That is where the electron transport chain comes in - the electron transport chain basically uses up the energy of electrons taken from food, = reduced NAD+, the NADH. Each NADH carries an electron (or it is two electrons, not sure here) and gives it to the electron transport chain. And in the chain, an energy of the electron is withdrawn and used for pumping of protons to the intermembrane space. Energy of each electron going through the electron transport chain provides for pumping of 10 protons together. For imagination, this is enough for an ATPase to produce about 3 molecules of ATP.

Which inventor made electrons?
A electron is one of the 3 things you need to complet a ATOM. getting back to the subject , so a electron is a thing in the ELECTRON CLOUD.
