[Solved] BIOL101 – Biomolecules of Cells Assignment



Biomolecules of Cells Assignment instructions



 The large molecules necessary for life that are built from smaller organic molecules are called biomolecules (biological macromolecules). There are four major classes of biomolecules, carbohydrates, lipids, proteins, and nucleic acids which are an important component of the cell. Combined, these molecules make up the majority of a cell’s mass. Foods you consume help to produce these 4 biomolecules needed for a healthy life. Carbohydrates can be found in almost all food sources and are an essential part of our diet. Lipids include a diverse group of compounds that are united by a common feature: they are hydrophobic.  Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Nucleic acids are key macromolecules in the continuity of life as they carry instructions for the functioning of the cell via DNA.


  • After researching Chapter 4 sections 4.3 through 4.7 of your text and utilizing additional research sources, answer the Nucleic Acids questions. Then answer one set of questions of the Carbohydrates, Lipids, or Proteins. When this assignment is complete, you would have answered the Nucleic Acids questions and one set of questions from either the carbohydrates or lipids or proteins.
  • When submitting questions/answers, maintain the number/letter identification for each set.
  • Submit your assignment as a word document.
