Question

During photosynthesis, plants use carbon dioxide, water, and light energy to produce glucose, C

6H12O6, and oxygen. The reaction for photosynthesis is represented by the balanced equation below.
6CO2 + 61120 + light energy – CH20; +602
State evidence that indicates photosynthesis is an endothermic reaction.

Answer 1

Photosynthesis is an endothermic reaction because it requires the absorption of light energy in order to proceed, which fits the definition of an endothermic process.

Step-by-step explanation:

The evidence that indicates photosynthesis is an endothermic reaction is that the process requires the absorption of light energy from the sun to convert carbon dioxide and water into glucose and oxygen. This energy input is necessary because photosynthesis involves the formation of chemical bonds in glucose, a process that requires energy.

If a reaction absorbs energy from its surroundings, it is considered endothermic, and this is seen in the photosynthesis equation: 6CO₂ + 6H₂O + Energy → C₆H₁₂O₆ + 6O₂. Since the reaction cannot proceed without an external source of energy (in this case, sunlight), it is characterized as an endothermic chemical reaction.
