Question 31 • 26-27 - C - RUSD Biology in the Living Earth
During photosynthesis, hydrogen ions build up inside the thylakoid, creating a higher concentration there than in the stroma. They flow down this concentration gradient through ATP synthase into the stroma, and the energy released drives the conversion of ADP to ATP. Therefore, the statement that describes this process and result is “Hydrogen ions flow from the thylakoid down a concentration gradient through ATP synthase channels into the stroma. ADP is converted to ATP.”
