1. Carbohydrate: Model Post Activity
Open your notebooks. Now review the notes and outlines. Think about what you learned.
Now, use your knowledge and notes to answer the questions in your notebook in complete sentences.

2. Identify the type of carbohydrate for each.
a. glucose d. galactose
b. maltose e. fructose
c. sucrose f. lactose
2. What chemical reaction is used to make a disaccharide?
3. All monosaccharides are isomers. Are all dissacharides isomers? Support.
4. List all types of atoms are found in all carbohydrates?
5. What is special about the hydrogen to oxygen ratio in carbs?
6. If you form a polysaccharide that contains 50 monosaccharides, how many water molecules are formed? How many glycosidic bonds (bonds between monomers) are formed?
7. If you wanted to break down the 50 polysaccharide into a 50 monomers, what would you need to do this?

3. Monosaccharides are Isomers

4. Disaccharides are Isomers

5. Review Isomers
Compare the number of carbons, hydrogens and oxygens in each
disaccharide. Does your observation support the concepts of isomers?

6. Why do organisms need carbohydrates?
Energy
Build Cell Structures

7. Carbohydrates: Energy Source
Readily Available
Storage
Glucose needed for Cellular Respiration (CR)
Glucose broken down and energy is release to be used.
CR chemical equation is C6H12O6 + O2CO2 + H2O
ATP is energy obtained from glucose
Carbohydrates that can provide energy for later use.
Usually polymers of glucose monomers like: starch (plants) and glycogen (animals)
Maltose and Sucrose are plant disaccharides that store energy

8. Carbohydrates: Structural Function
Cellulose – polysaccharide found in cell walls of plants
Chitin – polysaccharide found in cell walls of fungi and exoskeletons of insects
exoskeleton

9. Carbohydrate Review Monomers are the monosacchrides.
Dehydration Synthesis chemically joins a monosaccharide to a growing carbohydrate.
Hydrolysis breaks apart carbohydrates.
Glucose is used to provide energy.
Starch and Glycogen store energy for later use.
Disaccharides are part our our lives: sucrose and lactose
