Web Activity: Macromolecules in Cells

               1.          What is a macromolecule?
                 A macromolecule refers to a class of bigger and more important biology. They are the building blocks of cells.
       
                      2.          What is a monomer?
                Any of several smaller molecular structures that may be chemically bonded together to form long multi-part polymer molecules
       
                      3.          What is a polymer?
     A large molecule made up of similar or identical subunits called monomers.
        
                      4.          List the four main types of macromolecules.
                Proteins, lipids, carbohydrates, and nucleic acids.







5.          What are the types of reactions that macromolecules are shown to undergo?
Hydrolysis reactions, and dehydration synthesis(condensation reaction)


6.          Describe how monomers are joined together.
Monomers are joined together to form longer chains called polymers.

7.          Describe how polymers are broken down.
They go through Hydrolysis reactions.


8.     What is the specific name for the bond between simple sugar monomers?

Dehydration Synthesis

9. Which type of enzyme joins monomers together?
   Polymerase Enzyme


10. Describe how you had to arrange the sugar monomers in order to build a polysaccharide.
I added another monomer, two hydrogens, and one oxygen atom to create water.


11. Which building blocks of macromolecules are not used in building carbohydrates?
 Nucleotide, Amino Acids, and Fatty Acids. 

12. Why is sugar stored as glycogen in the human body?
   It is stored, so it can be used later as energy.

13. Why are plant foods essential to animal life?
   Animals try to take advantage of the plants to manufacture sugar and other   nutrients in them.

14. Describe how starch is digested by animals.
   Starch is going to be digested and stored as energy throughout the body.

15. What is "fiber" and why is it important in your diet?
   Fiber is a carbohydrate polymer thats important for digestive purposes. It can usually be found in fruit and vegetables.

 16. What causes you to pass gas according to the article?
   Fermentation of carbohydrates.

 17. What are some disadvantages of a low-carb diet?
  There are cardiovascular risk factors, these will affect the kidneys, and bone health.

 18. Describe the role that sugars play in cavity formation to your teeth.
   There are multiplicities in the bacteria, the sugars fuel these bacteria. This process causes cavities.
