How is photosynthesis an example of a chemical reaction?
As a result, the atoms end up in different combinations in the products. This makes the products new substances that are chemically different from the reactants. Photosynthesis is a series of chemical reactions that convert carbon dioxide and water into glucose (sugar) and oxygen in the presence of sunlight.
Is photosynthesis an endothermic chemical reaction?
Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun's electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant. Sunlight is the primary source of energy on the surface of Earth.
Why is photosynthesis considered a chemical reaction?
Photosynthesis is the process through which plants convert light energy into chemical energy. Here is the chemical reaction involved: water and carbon dioxide combine to form glucose and oxygen. Since new chemical species are formed, photosynthesis is clearly a chemical change.
Why is photosynthesis endothermic?
Photosynthesis is considered an endothermic reaction, because during the process of photosynthesis, energy from the sun or sunlight is being absorbed. Any chemical reactions that absorb heat energy from the surroundings to form products is termed the endothermic reaction.
Is photosynthesis exothermic or endothermic?
Photosynthesis is an endothermic reaction because sunlight energy is absorbed by green plants during this process.
Is photosynthesis exothermic or endothermic reaction Why?
Photosynthesis is an endothermic reaction because sunlight energy is absorbed by green plants during this process.
Why is photosynthesis referred to as endothermic while respiration as exothermic reaction?
As glucose is broken down into carbon dioxide, water, and ATP energy, the respiration reaction is exothermic. The photosynthesis reaction is endothermic because in the presence of sunlight and chlorophyll, carbon dioxide and water, or we can assume the heat is transformed into endothermic glucose reaction.

Why photosynthesis is called endothermic?
Photosynthesis is an endothermic reaction because sunlight energy is absorbed by green plants during this process.
Why is photosynthesis an endothermic?
As we all know, photosynthesis is a process in which green plants and other organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. Photosynthetic reactions involve absorption of direct sunlight and converting it to carbohydrates. So, it is considered to be an endothermic reaction.
How photosynthesis is exothermic?
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.
What is the heat of reaction for photosynthesis?
(Enthalpy change is the negative of heat of combustion.) Hence the enthalpy change for the respiration reaction is −2814 kJ mol−1, and so the enthalpy change for the photosynthesis reaction is +2814 kJ mol−1.
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.
