Which statements about chemiosmosis are true? Multiple select question.

Six carbon dioxide molecules combine with six 5-carbon compounds to form twelve 3-carbon molecules called 3-phosphoglycerate.

It is the mechanism by which ATP is produced as a result of the flow of electrons down a concentration gradient.

The chemical energy stored in ATP and NADPH is transferred to 3-phosphoglycerate molecules to form high-energy molecules.

As hydrogen ions (protons) move through ion channels across the thylakoid membrane, ATP is formed in the stroma.

The breakdown of water is essential for providing the protons (H+) necessary to drive ATP synthesis during chemiosmosis.
