Answer:
Yes, protons are pumped across the membrane, but flow right back again through the ATP synthase. More important is that illumination is required for carbon fixation. As photosynthesis runs, the chloroplasts remove CO2 from the water they are suspended in. In solution, CO2 forms carbonic acid, so removing CO2 will reduce the level of carbonic acid, raising the pH.
Explanation:
Chloroplasts are the primary cell organelles involved in the conversion of light energy into stable chemical energy through photosynthesis. The chloroplasts will become alkaline due to a rise in pH and a reduction in carbon dioxide.
Chloroplast is the green-colored cell organelle, primarily involved in the conversion of light energy into chemical energy.
When the isolated chloroplasts are illuminated, the suspension in which chloroplasts are suspended becomes alkaline. It is assumed that protons are pumped in from the medium to the thylakoids.
As photosynthesis takes place, the chloroplasts remove carbon dioxide from the suspension, which causes an increase in the pH of the suspension.
Therefore, the formation of carbonic acid from the CO2 will raise the pH.
