$ATPase$ enzyme consists of two parts. What are those parts? How are they arranged in the thylakoid membrane? Conformational change occurs in which part of the enzyme?

(N/A) The $F_{1}$ headpiece is a peripheral membrane protein complex located on the outer surface of the thylakoid membrane,facing the stroma. It contains the catalytic sites for $ATP$ synthesis from $ADP$ and inorganic phosphate $(Pi)$.
$(b)$ The $F_{0}$ part is an integral membrane protein complex embedded within the thylakoid membrane. It forms a transmembrane channel that facilitates the passive diffusion of protons $(H^+)$ across the membrane.
- Arrangement: The $F_{0}$ subunit is embedded within the thylakoid membrane,while the $F_{1}$ subunit protrudes into the stroma.
- Conformational Change: Conformational changes occur in the $F_{1}$ subunit of the $ATPase$ enzyme,which drives the synthesis of $ATP$.
