Protons

protons

stable elementary particles having the smallest known positive charge, found in the nuclei of all elements. The proton mass is less than that of a neutron. A proton is the nucleus of the light hydrogen atom, i.e., the hydrogen ion.

FADH2 in the Electron Transport Chain?

... oxidised, losing its electrons to the reduction of O to H20. In doing so, it changes to a lower energy state and the excess energy is used to pump protons from the matrix of the mitochondria to the outer membrane of the mitochondria. What I don't understand is what happens to FADH2. Is it exactly ...

ETC - purpose of having different dehydrogenases?

... complexes (more specifically, NDH-1 and NDH-2). One major difference between the two is the fact that NDH-1 is a coupling site (so pumps out protons while transferring electrons) while NDH-2 is not; will not pump out any protons. As a result of this, the NET ATP produced will be different. ...

Re:

... discharge' - which is noted for the fact that 'corona' is derived from the solar corona. In a converse point, solar activity streams a lot of protons (and thus positive ions) - which is a natural source of positive ions. If solar activity can generate positive ions naturally, then it wouldn't ...

Chemiosmosis, the movement of hydrogen ions to make ATP, was

A.Hydrogen ions build up as a result of the glycolysis. B. Protons diffuse from high concentrations to low concentrations. C. A fewer number of molecules of ATP are formed in cellular respiration due to chemiosmosis D. Hydrogen ions build up as a result ...

Re:

... of charge , but not movement of ions . Ions are not a force - an ion is a chemical molecule that does not have an equal number of electrons and protons. If you say that ions are transferred, that is equivalent to saying that there is a particular chemical that is being transferred. Your skin ...
