Answer :
Final answer:
During the light-dependent reactions in photosynthesis, water molecules are split to provide electrons in photosystem II.
Explanation:
The process that occurs during the light-dependent reactions in photosynthesis is water molecules are split. In this process, water molecules are split into oxygen, protons (H+), and electrons. This reaction takes place in the thylakoid membrane of the chloroplasts, specifically in photosystem II. The splitting of water molecules provides the electrons needed to replace the ones lost by chlorophyll during light absorption.
