Macromolecules Please answer the questions below as you read the CK12 sections assigned (Carbon, Carbohydrates, Proteins, Lipids, and Nucleic Acids). Make sure you are answering in complete sentences. Do not copy and paste information from the internet, and make sure your answers are in your own words. There are several short sections assigned for today's work. You do not need to do practice questions in CK12 unless you would like to for extra practice. See you tomorrow!
