is this right?

i thought that in cell respiration, atp synthase/electron transport chain pumps H+ into the matrix from the intermembrane space?

destroyer (172) says that the ETC pumps protons out of the matrix?

It is indeed ETC pumps protons out of the matrix (intermembrane space) and it creates electrical gradient and voltage gradient. Those protons flow back into the matrix via ATP synthases which generates ATP.

ohhhh. cliff's wasn't too clear on that i don't think. thank you.

Look at pg. 49 on cliff!
3. H+ ions are transported from the matrix to the intermembrane compartment 😉

And it's somewhat opposite to how it is the chloroplasts: high H+ inside thylakoids and low H+ in the stroma. (I think? lol)

yeap, you're right. those high H+ will eventually get pumped out of thylakoids generating 1 ATP. 🙂
