CGlycolysis step inside cytoplasm
DLight reaction by photolysis
Answer & Solution
Correct answer: D. Light reaction by photolysis
1. The light reaction uses photon energy.
2. This energy splits water molecules in photolysis.
3. The output is electrons, protons and O2.
4. So water splitting is in the light reaction.
