Questions & Step-by-Step Solutions

Which process occurs during the light reactions of photosynthesis?
  • Step 1: Light energy from the sun is absorbed by chlorophyll in the plant's leaves.
  • Step 2: This light energy is used to split water molecules (H2O) into hydrogen and oxygen.
  • Step 3: The splitting of water produces oxygen gas (O2), which is released into the air.
  • Step 4: Electrons are released from the water molecules and are used in the photosynthesis process.
