The Process of Photolysis ____

Question

The process of photolysis ____.  
A) is a function of the cyclic pathway
B) involves photosystem I
C) involves the splitting of visible light into its components
D) is the source of water in photosynthesis
E) directly replaces electrons lost by P680

Accepted Answer

Photolysis is the process in which water molecules are split into hydrogen ions, electrons, and oxygen in the presence of light. This occurs in photosystem II, where the electrons lost by P680, the reaction center chlorophyll of photosystem II, are replaced by the electrons generated from the splitting of water. This is essential for the continuation of the electron transport chain in photosynthesis.
