The splitting of water molecules during photosynthesis is called:

Answer: photolysis.

  • A photolysis
  • B glycolysis
  • C hydrolysis
  • D electrolysis

Correct answer: A. photolysis

Explanation: Photolysis is the light-driven splitting of water, releasing oxygen.

Photosynthesis: Inputs and OutputschloroplastLeaf cellSunlightCO2H2OO2Glucose

Simplified photosynthesis diagram: light energy, CO2, and H2O enter the leaf and are converted in the chloroplast into glucose and O2.

Concept context

Light reactions, the Calvin cycle, C 3 /C 4 /CAM pathways, photorespiration, and factors affecting the rate of photosynthesis. One of the highest-yield NEET chapters.
