One product of photosynthesis is glucose (sugar), which provides the basis for most food chains. The second product of photosynthesis is oxygen which comes in handy if your happen to be an aerobic organism that requires oxygen for survival.
An end product of Photosynthesis is actually a molecule that is a forerunner to glucose; that is, it's used to make glucose. This is called G3P. The Hydrogen carriers involved in either process are different, as well; cellular respiration uses NADH and FADH2 (in their reduced forms), while photosynthesis uses NADPH.
