Question

Based on this model, which statement best compares the amounts of energy in the reactants and products of photosynthesis? A. Since the process of photosynthesis makes new energy, the combined energy in the bonds of O2 and C6H12O6 is greater than that in the bonds of CO2 and H2O. B. Since making sugars uses energy, the combined energy in the bonds of CO2 and H2O is greater than that in the bonds of O2 and C6H12O6. C. Since the reactants of photosynthesis provide energy, the combined energy in the bonds of CO2 and H2O is greater than that in the bonds of O2 and C6H12O6. D. Since sugar stores the energy from light, the combined energy in the bonds of O2 and C6H12O6 is greater than that in the bonds of CO2 and H2O.

Answer 1

The correct statement is that the combined energy in the bonds of glucose and oxygen is greater than in the bonds of carbon dioxide and water because glucose stores the energy from light absorbed during photosynthesis.

Step-by-step explanation:

The correct statement that compares the amounts of energy in the reactants and products of photosynthesis is: Since sugar stores the energy from light, the combined energy in the bonds of O2 and C6H12O6 is greater than that in the bonds of CO2 and H2O. This indicates that the products, glucose (C6H12O6) and oxygen (O2), retain the energy that was initially absorbed from sunlight and converted during photosynthesis.

The process of photosynthesis uses solar energy to convert carbon dioxide and water into glucose and oxygen. The overall chemical reaction can be summarized as 6CO2 + 6H2O + energy → C6H12O6 + 6O2. The glucose that is produced acts as an energy-storing molecule, which indicates that it has a higher energy content than the reactant molecules, CO2 and H2O.

Answer 2

D. Since sugar stores the energy from light, the combined energy in the bonds of O2 and C6H12O6 is greater than that in the bonds of CO2 and H2O.

Step-by-step explanation:

A. Since the process of photosynthesis makes new energy, the combined energy in the bonds of O2 and C6H12O6 is greater than that in the bonds of CO2 and H2O. No. Photosynthesis does not make NEW energy. It converts the sun's energy into chemical bond energy.

B. Since making sugars uses energy, the combined energy in the bonds of CO2 and H2O is greater than that in the bonds of O2 and C6H12O6. No. Energy from the sun is added to the energy brought in by the CO2 and H2O.

C. Since the reactants of photosynthesis provide energy, the combined energy in the bonds of CO2 and H2O is greater than that in the bonds of O2 and C6H12O6. No. This ignores the main energy source: the sun.

D. Since sugar stores the energy from light, the combined energy in the bonds of O2 and C6H12O6 is greater than that in the bonds of CO2 and H2O. Yes. Photosynthesis is nature's way of capturing light energy and converting it to a form of energy that can be stored in the form of chemical bonds that can be released at a future time, as needed.
