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?
Two parts of the enzyme are ATPase: the head of F0 and the head of F1. The F0 head is towards the thylakoid’s inner side while F1 is towards the thylakoid's outer side. In F1 part of the enzyme, the conformation changes.
