5. Unit 4: Guiding Questions
What molecules are found in all living organisms?
Why do we need to eat a balanced diet that contains a variety of foods?

6. Objectives
SWBAT define macromolecule and identify the four biological macromolecules found in ALL living things.
SWBAT identify the monomers that compose each of the major macromolecules.

7. Introduction Biology is the study of LIFE
“Bio” means life
Therefore, we will begin our study of life by learning about the molecules found in all living things.

8. Molecules
Key Point: Two or more atoms of any element bonded together are known as a molecule

9. Atoms + Elements A pure substance containing one type of atom
Basic unit of matter

10. Polymers
Key Point: Polymers are large molecules made up of many smaller, repeating units known as monomers
“Poly” means many
“Mono” means one
Another name for polymers is macromolecules
“Macro” means large

11. Macromolecules
Key Point: The four macromolecules found in all living organisms are proteins, carbohydrates, lipids, and nucleic acids
Each of the four macromolecules contains the elements carbon (C), oxygen (O), and hydrogen (H)
They are considered organic molecules because they all contain carbon

12. Proteins Key Point: Proteins are made up of amino acids
The amino acids are joined together by peptide bonds
Amino acids contain carbon, oxygen, hydrogen, and also nitrogen.

13. Carbohydrates Key Point: Carbohydrates are made up of monosaccharides
Another name for carbohydrates is polysaccharides
Carbohydrates only contain carbon, hydrogen, and oxygen

14. Lipids
Key Points: Lipids are most commonly made up of fatty acids and glycerol
One of the main types of lipids is fats, also known as triglycerides (1 glycerol, 3 fatty acids)
Fats can be saturated or unsaturated
Lipids contain mostly carbon and hydrogen, but also oxygen.
Saturated fats= no double bonds
Unsaturated fats= double bonds

16. Nucleic Acids Key Point: Nucleic acids are made up of nucleotides
Every nucleotide contains a sugar, phosphate, and a nitrogen base

17. Summary
All cells contain proteins, carbohydrates, lipids, and nucleic acids
Proteins are made up of amino acids
Carbohydrates are composed of monosaccharides
Many lipids are made up of fatty acids and glycerol
Nucleic acids are composed of nucleotides

18. Macromolecules modeling
Materials: Notebook paper, macromolecule slip, a moderately decent and non-apathetic attitude
