Hydrogen ions rush out of the thylakoid, powering the reaction that produces ATP best describes what happens when the ATP synthase molecule opens. Thus, the correct option is C.
What is the function of ATP synthase in photosynthesis?
In the chloroplast, ATP synthase catalyzes the light navigated synthesis of ATP and is activated in the light. It is inactivated in the dark by redox-modulation through the thioredoxin system. It has been proposed that this down regulation is important for ward off wasteful hydrolysis of ATP in the dark.
The hydrogen ions are permits to pass through the thylakoid membrane through an embedded protein complex known as ATP synthase. This same protein produced ATP from ADP in the mitochondria. The energy produced by the hydrogen ion stream permits ATP synthase to attach a third phosphate to ADP, that forms a molecule of ATP in a process known as photophosphorylation.
The flow of hydrogen ions through ATP synthase is known as chemiosmosis, because the ions transport from an area of high to low concentration through a semi permeable structure in the cell.
