Where in the cell do electron transport chain occur?

In the mitochondria. The complexes need for the electron transport chain are attached on the inner side of the inner mitochondrial membrane, which channels opening into the intermembrane space for pumping out protons.

Where does electron transport chain happen?

It occurs in the inner mitochondrian membrane. it is most commonly used to produce energy in the mitochondria, however, it can occur in chloroplasts (in which case, it would occur in the thykaloid)


Where does a Electron Transport Chain happen?

In aerobic respiration, electron transport occurs inside the mitochondria. In photosynthesis, electron transport occurs inside the chloroplasts.


What job does the electron transport chain accomplish in order to drive the formation of ATP?

The proteins in the electron transport chain pump protons from the matrix of the mitochondria to the intermembrane space, thus establishing an electrochemical gradient

What portion of the mitochondria has the lowest pH?

According to another answer to a similar question here on this site, "The intermembrane space has the lowest pH, highest concentration of H+, due to the gradient created by the electron transport chain."
