1. Biology I: Introduction to
Bio-molecules
Mr. Nettles

2. Agenda-Wed., Sept. 7, 2011
1. Warm-Up – 5 min
2. Lesson – 30 min
3. Wrap-Up – 5 min
4. Cell Projects (due Fri.) – 20 min

3. Today’s Objectives
• I will identify and distinguish
between the four major groups of bio
(organic) molecules.
• I will articulate five key things about
lipids and proteins.

4. Warm-Up
1. What is the monomer of a nucleic acid?
2. What two organelles are related to
carbohydrates ?
3. This an example of a___________.
A. Sugar B. Protein C. Nucleic Acid

5. For each (bio) organic molecule, you
NEED to know 5 things!
1. AKA (other names): other names it can be
called
2. Monomer (building block): name of the
monomer
3. Purpose (what it does): job in our bodies
4. Examples: things that are that organic
molecule
5. Related organelles: what organelle it has to
do with

6. Lipids
• AKA: Fats, oils, waxes

7. Lipids
• AKA: Fats, oils, waxes
• Monomer: fatty acid

8. Lipids
• AKA: fats, oils, waxes
• Monomer: fatty acid
• Purpose: form boundaries (makes up
the cell membrane!)

9. Lipids
• AKA: Fats, Oils, Waxes
• Monomer: Fatty Acid
• Purpose: form boundaries (makes up the
cell membrane!)
• Examples: lard, vegetable oil

10. Lipids
• Related organelle:
-Cell/Plasma membrane: made
of lipids!

11. Lipids
Think!
• What are the monomers of lipids called?
• Give one example of a lipid.

12. Proteins
• AKA: enzymes, polypeptides
– Enzymes make up a significant part of the cell
membrane in living organisms.

13. Proteins
• AKA: enzyme, polypeptide
• Monomer: Amino Acid

14. Purpose: What do proteins do?
• Some control the rate of reactions and
regulate cell processes.
• Some are used to form bones and
muscles.
• Others transport substances into or out of
cells to help fight diseases.

15. Proteins
• AKA: enzyme, polypeptide
• Monomer: Amino Acid
• Purpose: Do the work of the cell !!

16. Proteins
• AKA: enzyme, polypeptide
• Monomer: Amino Acid
• Purpose: Do the work of the cell !!
• Examples: enzymes, lactase,
hemoglobin, insulin (suffix ‘ase’)

17. Proteins
• Related Organelle:
-Ribosome: makes proteins!

18. Proteins
Think!
• What are the monomers of proteins
called?
• Give one example of a protein.

19. Carbohydrates, Nucleic Acids,
Lipids, or Proteins?

21. Amino Acids

22. Form Boundaries

24. Monosaccharides

25. Does the work of the cell
- carries out different cell functions like
fighting disease and transporting substances
in and out of the cell

27. Starch

28. Carry genetic information

30. Lactose

31. Nucleotides

33. DNA and RNA

34. Fats and Oils

36. Energy Production and Storage

37. Polypeptides

39. Lactase

40. Cell Membrane

42. Wrap-Up
1. What is the monomer of a lipid?
2. Give two examples of proteins?
3. Phosphatase is a __________.
A. Lipid B. Protein C. Sugar
