It has two components: Fo (membrane-embedded) and F1-ATPase (in the matrix), capable of producing over 100 ATP molecules per second. Additionally, it can convert mechanical energy into chemical energy, synthesizing ATP from ADP and Pi at a rate of about 5 ATP molecules per second through rotation, as demonstrated in research using magnetic beads and a rotating magnetic field.

It describes how altering the thylakoid pH by using acidic mediums allows chloroplasts to synthesize ATP in alkaline conditions with ADP and inorganic phosphate, showcasing the role of the proton gradient in ATP production even in the absence of light.
