During the process of photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. The equation for this reaction is: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂ Which statement is true about the energy changes in this reaction?

Question

During the process of photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. The equation for this reaction is: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂ Which statement is true about the energy changes in this reaction?

A. The reaction is exothermic because the energy from the products is higher than the energy from the reactants.
B. The reaction is exothermic because energy is released when glucose is formed.
C. The reaction is endothermic because light energy is absorbed to break the bonds in water and carbon dioxide.
D. The reaction does not involve energy changes.

The correct statement about the energy changes in the process of photosynthesis is:

C. The reaction is endothermic because light energy is absorbed to break the bonds in water and carbon dioxide.

Photosynthesis requires an input of energy (in the form of sunlight) to convert carbon dioxide and water into glucose and oxygen, meaning that it is an endothermic reaction. This energy is used to break the bonds in the reactants (CO₂ and H₂O) and to form the products (C₆H₁₂O₆ and O₂).
