ATP synthase enzyme consists of two parts:
(a) $\mathrm{F}_1$-head piece is a peripheral membrane protein complex and contain the site for synthesis of ATP from ADP+ pi (inorganic phosphate).
(b) $\mathrm{F}_0$-integral membrane protein complex that form the channel through which proton cross the inner membrane.
The arrangement of $\mathrm{F}_1$ and $\mathrm{F}_0$ in thylakoid membrane is as follows.
$\mathrm{F}_0$ - is a portion present within the thylakoid membrane.
$\mathrm{F}_1$ is a portion of ATP synthase enzyme present in the stroma of chloroplast.
The conformational change occurs in $F_1$ portion of ATP synthase thus, it facilitates the ATP synthesis.
