Hi, does the electron transport chain actually PRODUCE ATP? It says on my sheet that 4 molecules of ATP are produced in this way.

Since this is not my area of expertise, I searched Google under the key words "electron transport chain ATP" to get these possible sources:

I hope this helps. Thanks for asking.
