Study Guide Two: Food Molecules ( Macromolecules)

Directions : The following questions should be answered  on a Google Doc to be submitted on Google Classroom.  Be sure to do all of the work: A. Carbohydrates, B. Lipids, C .Nucleic Acids ,and all of the questions , including the KEY Question.

Use  web resources. 

                                                                                            Hemoglobin =a protein Molecule

Standard : BIO.A.2.2.3: Compare and contrast the structure and function of carbohydrates, proteins, lipids, and nucleic acids in organisms.

Learning Target: I will be able to name macromolecules and identify the structures and functions of particular examples of macromolecules.
