 I think it is important that we take a look at atoms and macromolecules because it does help understand why organism are the way they are.  Enzymes play a huge part in life. We cannot drink or eat some sources of energy because we don't have the appropriate enzyme. Enzymes restrict living organisms' intake and creation. 

However, it is not easy to understand how the bonds and associations between them happen. For me it is difficult to study atoms and molecules without fully knowing all there is to know.
