Hi, I'm Dan Weisenberger, and this is what kind of pathway does photosynthesis involve. Well, photosynthesis is a biochemical pathway which involves a series of chemical reactions that are catalyzed by enzymes in order to convert light energy, carbon dioxide and water into sugars and oxygen. Now this is a very complicated and involved process, but I think we can distill it down to three main steps. One, is that we have to have chlorophyll in the chloroplasts of plant cells to absorb light from the sun. Secondly, we use the light energy after that absorption to split water molecules into oxygen, electrons and protons, which then help to facilitate the process of using sugar and converting it, or I'm sorry, using carbon dioxide and converting it into sugars via the Calvin Cycle. And sugars can then be used for glycolysis, citric acid cycle, oxidative phosphorylation, with the key of generating energy. Then oxygen would go into the atmosphere for animals to breathe. I'm Dan Weisenberger, and this is what kind of pathway does photosynthesis involve.
