Where do the protons used to drive chemiosmosis during
photosynthesis come from?

Option C, Cell Y

Explanation:

Prokaryotic cells are the most primitive type of organism that do not possess a true nucleus in them. They do not even have true membrane-bound organelles.

The prokaryotes have a plasma membrane as their protective covering which helps them to survive in extreme conditions.

They also possess a rigid cell wall which also provides them protection and rigidity. Example: Archaea and bacteria.
