What is the role of ATP synthase in chemiosmosis?

• It stores energy in the form of glucose

• It breaks down ATP to release energy

• It transports protons across the membrane

• It produces ATP by using the energy from the flow of protons.

What is the relationship between the electron transport chain and oxidative phosphorylation?

• Oxidative phosphorylation occurs in the cytoplasm, while the electron transport chain occurs in the mitochondria.

• Oxidative phosphorylation is the process of generating ATP from the transfer of electrons in the electron transport chain.

• The electron transport chain is not involved in the process of oxidative phosphorylation.

• Oxidative phosphorylation is the process of breaking down ATP to generate electrons for the electron transport chain.
