Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
During electron transport along the chain, electron carriers alternate between reduced and oxidized states as they accept and donate electrons. Each component of the chain become reduced when it accepts electrons and returns to its oxidized state as it passes along electrons.
As electrons move along the chain of molecules known as the electron transport chain, they lose energy, which is then used by the cell to make ATP.
They lose energy,which is then used by the cell to make ATP
it will move faster
In a covalent bond electrons are shared.
Electrons are transferred from one element to another. when electrons are shared this is a covalent bond.
Electrons may be transferred from one particle to another.
what happens is when it binds to the electron.... you lose mass(Weight). Isic Newton's theory explains it all
Electrons are negatively charged. They cannot be positively charged or neutral.
they move through an electron transport chain to photosystem 1
They begin to electrolyze, a term used for giving off static charge.

The electron transport chain happens in the cristae membrane inside the mitochondria.
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." (Sherwood 36) References: Sherwood, Lauralee. Human Physiology: from Cells to Systems. 7th ed. Australia: Brooks/Cole, Cengage Learning, 2010. Print.
as electrons from the Krebs cycle move down the electron transport chain energy level is reduced.
During electron transport in the mitochondrion, protons (H+) accumulate in the intermembrane space. This happens as electrons are transferred through the electron transport chain, creating a proton gradient across the inner mitochondrial membrane. This gradient of protons is later utilized by ATP synthase to generate ATP through oxidative phosphorylation.
Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.
