Which statement is most accurate concerning how photosystem II (PS II) compares to the electron transport chain (ETC) of mitochondria?

In both systems, ATP is produced by chemiosmosis.

According to the Z scheme, what is the path of electrons through photosystem I (PS I) and photosystem II (PS II)?
