Where do the electrons that are excited by the energy in sunlight first come from?

Question

Quizplus · Accepted Answer

The electrons that are excited by the energy in sunlight first come from water, which is split into oxygen, hydrogen ions, and electrons during the light-dependent reactions of photosynthesis. This process is known as photolysis or water splitting. The excited electrons are then transferred through a series of electron carriers, ultimately leading to the production of ATP and NADPH, which are used in the light-independent reactions to produce glucose.
