Answer #1

Answer: Photolysis of water is the source of oxygen in photosynthesis.

Other options are wrong because;

  • Proteins function in electron transport during photosynthesis.
  • Membranes are locations where the electron transport chain takes place.
  • Carbohydrates are glucose, fructose, sucrose, etc., which are products of photosynthesis.
  • Chlorophyll helps plants absorb energy from light.
  • The energy of the Photon causes the pigment to go into an electronically excited state, thus enabling photosynthesis.
