Statement I: A part of ATP synthase enzyme called the cF1 is embedded in the membrane of thylakoid forming a transmembrane channel that carries out facilitated diffusion of protons across the membrane. Statement II: Another portion of ATP synthase called cF0 protrudes on outer surface of the thylakoid membrane towards the side facing the stroma.

• ATPase enzyme has two parts; one called the

F_{0}

is embedded in the membrane of thylakoid and forms a transmembrane channel that carries out facilitated diffusion of protons across the membrane.
• The other portion is called

F_{1}

and protrudes on the thylakoid membrane on the side that faces the stroma.
