Each class of molecule has features that determine its use in living systems. The first class of molecules are called carbohydrates.

  No, it is organic. Cellulose is a polymer (chain) of glucose molecules. Each glucose residue (unit) is organic, too. There is no easy definition of an organic molecule â¦ , but it must contain carbon.However, simple carbon compounds (for example, calcium carbonate and carbon dioxide) are inorganic.From a biologist's point of view, organic compounds contain a relatively large amount of energy.here is no easy definition of an organic molecule â¦ , but it must contain carbon.
