The ATP synthase consists of two parts where:
1. is a transmembrane channel and protrudes out towards stroma
2. is a transmembrane channel and protrudes out towards stroma
3. is a transmembrane channel and protrudes out towards lumen of thylakoid
4. is a transmembrane channel and protrudes out towards lumen of thylakoid

Chemiosmosis in chloroplasts is possible because of:
1. establishment of a proton gradient across the thylakoid membrane.
2. diffusion of electrons through the ATP synthase.
3. osmosis of water from thylakoid to stroma.
4. presence of large amount of oxygen in the stroma.
