1. Get a paper from the front and answer the warm-up questions at the top
1. What is the difference between organic and inorganic molecules? 2. Which molecules is organic? (Circle your choice) CO2 C6H12O6 NH4 H2O 3. What makes something acidic? 4. What makes something a base? 5. Which pH is a neutral, an acid, and a base? a. pH 7= b. pH 11= c. pH 3=

2. Check your answers
1. Organic molecules have carbon and hydrogen, while inorganic doesn’t have carbon and hydrogen together. 2. Which molecules is organic? (Circle your choice) CO2 C6H12O6 NH4 H2O 3. If the pH is between 0 and 6.9 it is acidic. 4. If the pH is between 7.1 and 14 it is a base. 5. Which pH is a neutral, an acid, and a base? a. pH 7= neutral b. pH 11= base c. pH 3= acid

4. Let’s fill in our sheet, I know you’re excited

5. 1. There are 6 elements essential for life. They are:
C= Carbon
H= Hydrogen
O= Oxygen
N= Nitrogen
P= Phosphorous
S= Sulfur
The most important element is CARBON!
It’s most important because Carbon forms the backbone of important molecules.

6. 2. There are 4 important macromolecules (polymers) 3
2. There are 4 important macromolecules (polymers) 3. Macromolecules are made of monomers (subunits)

7. 4. Macromolecules (polymers) are like houses, and monomers are like the bricks used to build it.

8. 5. The 4 macromolecules are:
Carbohydrates
Lipids
Nucleic Acids
Proteins

9. Macromolecules (or polymers) are made of Monomers (aka subunits).

10. Guided Biochemistry Reading:
We’ll read the section together, then answer the questions before we go into the notes.

11. Guided Biochemistry Reading Questions:
1. What are all living things and food made of? 2. What are the four types of organic molecules? 3. What are carbohydrates and what do we use them for? 4. What are lipids and what do we use them for? 5. What are proteins made of and what do we use them for? 6. What are the monomers of nucleic acids and why are they important?
A.L.T. are made of macromolecules
There are carbohydrates, lipids, proteins, and nucleic acids
Carbs are sugar that provide energy for cells
Lipids are fats and oils that are long term energy sources
Proteins are made of amino acids and provide cell structure
Nucleic acids are made of nucleotides and they provide directions for the cell to live

12. We’ll fill out the carbohydrates notes together so you know how to fill out the rest of the paper

13. Carbohydrates
Carbohydrates are made of Carbon, Hydrogen, and Oxygen in a 1:2:1 ratio. (1 Carbon to 2 hydrogen to 1 oxygen atoms)

14. Carbohydrates Monomer= Monosaccharides
Many monomers together form a Polysaccharide
Examples in plants:
Starch = storage
Cellulose = structure

15. Monosaccharide: Glucose Polysaccharide: Starch

16. This is funny because potatoes are made of starch which is a polysaccharide (complex carb)

17. Functions: Carbohydrates Energy Structure and Support
Monosaccharide= immediate energy
Structure and Support
Identifiers on the surface of cell membranes.

18. Now it’s your turn:
Go from station to station and collect the information to fill out your note sheet.
Once you finish filling out your notes, finish your biochemistry vocabulary paper from last week (this is due tomorrow).
If you finish this today Mr. Shimko will check it to give you credit for your work

19. Get a legal size piece of paper from the front of the room

20. Placemat activity Procedure: Divide your placemat into 4 sections.
Leave room at the top for a creative title
Label the sections with the following: Carbohydrates, Lipids, Nucleic Acids, and Proteins
Each section needs to have the following:
Elements Present in that macromolecule
Monomers
Examples of that macromolecule
3 Functions of that macromolecule
Drawing of the monomer AND polymer
3 pictures of food that have that macromolecule.

21. Placemat Rubric: Title=1 pt Heading for each section= 8 pts
Monomers= 4 pts
Correct elements= 4 pts
Functions= 8 pts
Examples= 4 pts
Drawings= 8 pts
Pictures of food= 8 pts
Neatness and Creativity=5
Total= ______/50
