Which number remains unchanged during photosynthesis?(1 point) Responses the number of carbon atoms the number of carbon atoms the number of carbon dioxide molecules the number of carbon dioxide molecules the number of water molecules the number of water molecules the number of glucose molecules

Answer 1

During photosynthesis, the number of carbon atoms remains unchanged. Photosynthesis converts carbon dioxide (CO₂) and water (H₂O) into glucose (C₆H₁₂O₆) and oxygen (O₂). While the number of carbon dioxide molecules used may change, the total number of carbon atoms involved in the reactants and products remains consistent. Specifically, 6 carbon atoms from 6 molecules of CO₂ are ultimately transformed into 1 molecule of glucose, which also contains 6 carbon atoms.
