Question

Why is photosynthesis referred to as a biochemical pathway?

Answer 1

Because it is a series of sequential chemical reactions that are catalyzed by enzymes and occur on a cell.

By taking a look of the definition of a biochemical pathway, we can see that the process of photosynthesis totally fits in the definition.

Where carbon dioxide (`CO_2`) and water (`H_2O`) are converted into glucose (`C_6H_12O_6`) and oxygen (`O_2`).
