The Electron Transport Chain

This occurs on the cristae of the mitochondrion. A maximum of 34 ATP are produced at this stage. 

NADH2 and FADH2 are electron transporters that bring Hydrogen ( which is an electron donator) to the cristae NADH2 and FADH2 are oxidised( this means that they lose their hydrogen) The hydrogen forms an electron and a proton which can be used in chemiosmosis ( think about this you have a semi permeable membrane and concentration gradients- sound familiar?)

The electrons that have a high energy ( which are high energy ones as they are in the 1s orbital of the atom near to the nucleus which makes it harder to remove…
