The H⁺ (protons)accumulate in the thylakoid space during electron transport between photosystems I and II.The excess of protons in the thylakoid space A)enters the photorespiration pathway. B)raises the pH of the space until the processes stop. C)is small enough to diffuse back out through the lipid bilayer. D)converts NADP to NADPH and generates ATP in the process. E)moves from the thylakoid space to the stroma through the ATP synthase complex.

Question

Quizplus · Accepted Answer

The excess of protons in the thylakoid space moves from the thylakoid space to the stroma through the ATP synthase complex, where it is used to generate ATP in the process of chemiosmosis. This movement of protons down their concentration gradient is facilitated by the ATP synthase complex, which acts as a proton channel and an enzyme that catalyzes the synthesis of ATP from ADP and inorganic phosphate. This process is known as photophosphorylation and is an essential part of the light-dependent reactions of photosynthesis.
