How is the energy and matter used in photosynthesis?

• The bonds in glucose and oxygen molecules are broken apart by light energy and the carbon, hydrogen, and oxygen atoms are rearranged to form the molecules carbon dioxide and water.

• The atoms of carbon, hydrogen, and oxygen are broken apart by light energy and put back together to make different atoms of hydrocarbons.

• The bonds in carbon dioxide and water molecules are broken apart by light energy and the carbon, hydrogen, and oxygen atoms are rearranged to form the molecules oxygen and glucose.

• Plants keep this a closely guarded secret

Which photosynthesis equation is correct?

• C₆H₁₂O₆ + 6H₂O → 6O₂ + 6CO₂ + ATP

• sunlight + C₆H₁₂O₆ + 6H₂O → 6O₂ + 6CO₂

• sunlight + 6O₂ + 6CO₂ → C₆H₁₂O₆ + 6H₂O

• sunlight + 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂
