What type of reaction is photosynthesis, the process where carbon dioxide combines with water to form glucose in the presence of sunlight?
I would classify these as a redox reaction.
light reaction
Endothermic
Photosynthesis is a chemical reaction known as a combination reaction. It is a process that converts carbon dioxide and water into glucose and oxygen, using energy from sunlight. Specifically, photosynthesis is classified as an endothermic redox reaction, as it involves the transfer of electrons from one molecule to another. In this case, water molecules are split into hydrogen and oxygen atoms, with the hydrogen being used to reduce carbon dioxide and form glucose. The overall reaction can be represented by the equation:
6CO2 + 6H2O + sunlight energy → C6H12O6 + 6O2
By classifying photosynthesis as a combination reaction, we can understand that it involves the joining of two or more substances to form a new compound. In this case, carbon dioxide and water combine to form glucose, while releasing oxygen as a byproduct.
