Cellular Respiration -- Step Four: Oxidative Phosphorilation (Electron Transport Chain)

[Tougain]

this is absolutely WRONG!! the movement of the H+ back into the matrix via channel proteins which work as ATPase provides energy and this energy causes the ADP and inorganic phosphate to combine and make ATP, it isnt that H+ combines with ADP this is wrong and LOTS of steps are missing, its a well worked summary and good points here and there but it leads to a wrong explanation.

@Tougain Hi "Tougain" I thought that the movement of electrons along the electron transport carrier molecules result in oxidation-reduction reactions, which as a result causes the electrons to lose energy. This energy is then used to combine an inorganic phosphate molecule and ADP to form ATP. Please clarify if I am incorrect. Thankyou.

@mrvink01 What you said at the beginning is correct "the movement of electrons along the electron transport carrier molecules result in oxidation-reduction reactions, which as a result causes the electrons to lose energy" but this energy is not used to combine the inorganic phospahte and ADP molecule, this energy is rather used to actively transport hydrogen ions from the matrix to the space betwwen the inner and out membrane, this builds up a high concentration of H+'s

@Tougain in that membrane space and then what happens I've mentioned in the next comment they diffuse "BACK". its mentioned in my next comment

[mrvink01]

@Tougain Thankyou I understand now

tnx

In the electron transport chain, electrons drop in free energy as they go down the chain and are finally passed to O2 forming H2O, water.

The protons don't bind with ADP to form ATP...confusing in your animation !

thanks very helpful

[darkandlovely2007]

its actually 30 ATP molecules. Because energy is used to move molecules around.

you've saved me so much time!! Thanks a lot

[Smellychicken]

where's ATP synthase! aghhhhhh

didn't help, music was great tho
