Answer
True
Work Step by Step
The water-splitting enzyme in photosystem II, also called the oxygen-evolving complex, is responsible for extracting electrons from water molecules to replace those lost by chlorophyll during photosynthesis. This process requires the removal of four electrons from two water molecules, which can produce highly reactive superoxide radicals. To prevent these radicals from escaping, the reaction intermediates are kept tightly bound within the enzyme complex until O2 is released.
