Suppose the interior of the thylakoids of isolated chloroplasts were made acidic and then transferred in the dark to a ph-8 solution. what would be likely to happen? a. the isolated chloroplasts will make atp b. the calvin cycle will be activated c. cyclic photophosphorylation will occur d. only a and b will occur e. a, b and c will occur

The correct answer will be option-A

Explanation:

Thylakoid is the structure in the chloroplast where the light-dependent reaction takes place which forms the ATP and NADPH.

The production of ATP takes place due to the movement of Hydrogen ions across the membrane from the interior or lumen to the stroma of the chloroplast.

If the thylakoid were made acidic that is hydrogen ion concentration increases inside the lumen and then kept in a basic solution where the hydrogen concentration is low then it will lead to generation of a proton gradient.

The generation of the proton gradient will cause the movement of the protons from the lumen to the outside through ATP synthase which will produce ATP.

Thus,  option-A is the correct answer.
