Both chloroplasts and mitochondria use the process of chemiosmosis to produce ATP. Which of the following explains how this mechanism differs in these two structures? Chloroplasts require electron carriers to transport high-energy molecules, while mitochondria store them in the mitochondrial matrix.
Chloroplasts use photosystems as a source of electrons, while mitochondria use water molecules as a source of electrons.
In chloroplasts, electrons move through an electron transport chain, while in mitochondria they undergo cyclic electron flow.
In chloroplasts H+ diffuses across the thylakoid membrane, while in mitochondria H+ diffuses across the inner mitochondrial membrane.
