Question

Suppose the interior of the thylakoids of isolated chloroplasts and then transferred in the dark to a $pH8$ solution. What would be likely to happen?

• A. The isolated chloroplasts will make ATP
• B. The Calvin cycle will be activated
• C. The cyclic photophosphorylation will occur
• D. Isolated chloroplasts will generate oxygen gas

Answer 1

The correct option is A The isolated chloroplasts will make ATP

The interior of the thalaoids of isolated chloroplast and then transferred in the dark to a pH 8 solution than the chloroplast will make ATP because due to an increase in pH abrupt ATP synthesis then accompanied the disappearance of the pH gradients across the thalaoid membrane.
