Is photosynthesis an example of an endothermic reaction?
Photosynthesis is considered an endothermic reaction because in this process solar energy is absorbed to produce glucose and oxygen from carbon dioxide and water in the presence of chlorophyll. (An endothermic reaction is one in which energy is utilized.)

Why is photosynthesis endothermic and not exothermic?
Photosynthesis is an endothermic reaction because sunlight is being absorbed during the reaction and the definition suggests that in a reaction if heat is being absorbed it is termed as an endothermic reaction.

Why is photosynthesis a endothermic reaction?
Photosynthesis is an endothermic reaction as it requires light energy to react carbon dioxide and water to produce glucose and oxygen. The light energy required is absorbed by a green pigment called chlorophyll in the leaves. Chlorophyll is located in chloroplasts in plant cells .

Is photosynthesis an example of an exothermic reaction?
One example of an endothermic reaction is photosynthesis. In photosynthesis, energy from light is stored in a high-energy product, glucose. An example of an exothermic reaction is cellular respiration. High-energy glucose releases energy as it’s broken down.

Why is photosynthesis considered an endothermic reaction explain with the equation?
In this process, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. This reaction requires 15MJ of energy (sunlight) for every kilogram of glucose that is produced: Sunlight+6CO2(g)+6H2O(l)⟶C6H12O6(aq)+6O2(g) Q.

How is photosynthesis an exothermic reaction?
In photosynthesis, energy from light is stored in a high-energy product, glucose. An example of an exothermic reaction is cellular respiration. High-energy glucose releases energy as it’s broken down. And that energy is used to generate ATP molecules.
