WebMar 10, 2024 · Answer: a. the pH within the thylakoid is less than that of the stroma Explanation: The pH of thylakoid membrane is 8 at normal conditions but it became highly acidic like 4 during photosynthesis. WebStromal pH after either 20 or 90 min of eye closure was 7.39 +/- 0.01 (n = 12, +/- SEM) and returned to 7.54 within 10-15 min of opening the eye, t1/2 = 3 min. Eye closure was simulated by exposing the eye to a gas mixture of 7.1% O2, 6.7% CO2, balance N2, which was passed through tight-fitting goggles.
