What three things are found in the thylakoid membrane?
Chlorophyll molecules: Responsible for capturing light energy during photosynthesis. Electron transport chain proteins: Facilitate the transfer of electrons during the light-dependent reactions. ATP synthase enzyme: Generates ATP by utilizing the proton gradient established across the thylakoid membrane.
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.

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 two things do you need for aerobic respiration to take place?
You need oxygen as the final electron acceptor in the electron transport chain, and glucose as the initial energy source to undergo glycolysis and generate ATP through the citric acid cycle and oxidative phosphorylation.
What 2 things are required for aerobic repiration?
Aerobic respiration requires oxygen and glucose. Oxygen serves as the final electron acceptor in the electron transport chain, while glucose is the primary source of energy, providing the necessary fuel for the metabolic pathways involved in the process. Together, they enable the efficient production of ATP, the energy currency of cells.
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).

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
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 does electron configuration tell you about an element?
Electron configuration tells you how electrons are arranged in an atom's energy levels. It provides information on the number of electrons in each energy level and helps predict an element's chemical properties and reactivity. By understanding electron configuration, you can determine an element's potential to form bonds with other elements.
The electron transport process makes water and ATP and is sometimes called?
Two different processes here.Oxidativephosphorylation.This is where highly electronegativeoxygen pulls electrons from the ETC, put them together with hydrogen ions and makes water.Chemiosmosis. Where the hydrogen ions that were pumped into the outer membrane of the mitochondria fall back down their concentration gradient through the ATP synthase and make ATP.
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.

What happens to the electron transport chain if oxygen is lacking?
The organism dies as no energy for even the simplest things, such as respiration and brain command, is available. Only in muscle cells can the organism switch to glycolysis for ATP production. The brain cells can not preform glycolysis.
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.
