When considering the hierarchy of biological organization, macromolecules are the last abiotic (i.e. non-living) “step” before the smallest functional living units cells. If organisms were not able to obtain these macromolecules, either through synthesis or ingestion, life could not exist. For this discussion you will be building on the foundation of the previous Module by defining what macromolecules are and using your knowledge of their molecular structure to explore how they “fuel” us via the process of cellular respiration.
First, you will need to write a 200-300 word post covering the following topics:
