Answer:

to test for liberation of O2 in the light

Explanation:

Photosystem II is protein complex located  in the thylakoid membrane of plants with the major role in light-dependent reactions of photosynthesis. Photons of sunlight are absorbed by photosystem II and electrons within the system consequently become excited (pass through the cofactors). Electrons are replaced by water and hydrogen ions and molecular oxygen are formed.
