Questions and Answers
What role does chlorophyll play in the light reaction?
What role does chlorophyll play in the light reaction?
Chlorophyll is energized by a beam of photons in the light reaction, releasing an electron and becoming ionized.
What is the result of water photolysis in the light reaction?
What is the result of water photolysis in the light reaction?
The photolysis of water in the light reaction releases oxygen and hydrogen ions.
How is the energy from the light reaction used?
How is the energy from the light reaction used?
The energy from the light reaction is used to form ATP.
Study Notes
- In the light reaction, a beam of photons energizes a molecule of chlorophyll, which then releases an electron and becomes ionized.
- This ionized molecule then photolyses water, releasing oxygen and hydrogen ions.
- The energy from the photolysis of water is used to form ATP.
- The light reaction is the first step in photosynthesis, which involves the breakdown of water molecules to liberate oxygen.
