3. What are the 6 most common elements found in all living things.
a. Carbon, Helium, Nitrogen, Oxygen, Potassium and Sodium b. Carbon, Hydrogen, Nitrogen, Oxygen, Potassium and Sodium c. Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus and Sulfur d. Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus and Sodium

4. Today you will
Identify the 4 types of macromolecules found in living things.

5. macromolecules

6. Carbon Because of its ability to bond to itself and other elements
Carbon has a central role in the chemistry of living organisms (organic chemistry).
Because of its ability to bond to itself and other elements
Carbon makes chain polymers (hundreds or thousands of carbon atoms long).

7. CARBON
Carbon is important biological element because it can form four bonds with other elements and long chains or rings
Polymer – large molecule made up of many smaller units like starch
Monomer – unit that makes up polymer; glucose is the monomer for starch

8. Carbon Chain

9. What does a living organism need?
Carbohydrates
Lipids (fat)
Proteins
Nucleic Acids

10. Carbohydrates Made up of: sugar molecules that are bonded together.
Simple sugars = simple carbohydrates
eg. glucose
Polymer of sugars = complex carbohydrate
eg. cellulose and glycogen
Function – energy source for living organisms

11. Releases energy for cells
Organic
Compound
Composed of:
Examples
Function
Carbohydrate
C, H, O
Sugar
Starch
cellulose
Releases energy for cells

12. Proteins Made up of: very long chains of amino acids
There are 20 different amino acids, which can combine in any order.
Proteins are very large and complex molecules.
Nitrogen plays an important part in proteins.

13. Proteins (cont.) Functions: Needed to build and repair body structures
Regulate processes in body
Example: hemoglobin found in red blood cells that helps carry oxygen to all the cells in the body

14. Used to build cell parts;
Organic
Compound
Composed of:
Examples
Function
Protein
C, H, O, N
enzymes
Used to build cell parts;
Made of smaller parts called amino acids
Where are proteins made in the cell…?

15. Lipids (fats, oils, and waxes)
Made up of:
Mostly carbon and hydrogen polymers (very long) that do not dissolve in water
Function:
Store energy
Make up cell membranes
Store vitamins
Insulation (keeping warm)

16. Stores and releases MORE energy for cells
Organic
Compound
Composed of:
Examples
Function
Lipid
C, H, O
Fats
Oils
Waxes
Stores and releases MORE energy for cells
Cell membranes are made of lipids

17. NUCLEIC ACIDS
Nucleic acids are the largest known organic molecules; made from thousands of repeating subunits called nucleotides
There are two major types of nucleic acids:
DNA
RNA

18. Stores hereditary information
Organic
Compound
Composed of:
Examples
Function
Nucleic Acid
C, H,
O, N, P
DNA
RNA
Stores hereditary information
