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

Answer:

                  ATP synthase enzyme has two parts (a) -head piece is a peripheral membrane protein complex and contain the site for synthesis of ATP from ADP +pi (inorganic phosphate). (b) -integral membrane protein complex that forms the channel through which proton cross the inner membrane. The. arrangment of  and  in thylakoid membrane is as follows -portion is present within the thylakoid membrane. -portion of ATP synthase enzyme is present in the stroma if chloroplast;: The conformational change occurs in f) portion of ATP synthase thus, facilitaling the ATP synthesis.
