Question

Quizplus · Accepted Answer

In a noncyclic pathway of photosynthesis, photosystem II captures photons and uses the energy to extract electrons from water molecules. These electrons are then passed down an electron transport chain to photosystem I, effectively replacing the electrons lost by photosystem I when it is excited by light.
