Before coming to class, you should have already reviewed the Tegrity lecture and the remaining part of chapter 2 in the textbook dealing with carbohydrates, lipids, proteins, and nucleic acids.

1.) List the 4 categories of organic macromolecules.

2.) In your own words, define what is meant by the term monomer now define polymer .

3.) Which organic macromolecule has a basic structure of 1 carbon:2 hydrogen:1 oxygen?

A. List examples of carbohydrate monomers:

B. What is the ending typically assigned to sugar molecules?

C. In your words, describe what is meant by a polysaccharide? What are some important examples of polysaccharides of glucose?

D. Which carbohydrate molecule is broken down by cells in order to make energy?

E. Which carbohydrate molecule is used to store energy in skeletal muscle cells?

F. What is the primary function of a carbohydrate?

4.) Which organic macromolecule has a basic structure of 1 carbon:2 hydrogens and is often described as a long hydrocarbon chain?

A. List out the different classes of lipids

Now go back to the list and highlight those lipids involved in either storing or making energy, place a * next to those lipids that are involved in the *structure* of the cell or tissue, and use bold on those lipids that are involved in communication.
B. Are lipids polar or nonpolar molecules? Is blood a polar or nonpolar solution? What does this mean about lipids and their ability to travel through the blood stream?

C. Which lipid molecule can be broken down by cells in order to make energy?

D. What is meant by a saturated fatty acid?

E. What is meant by an unsaturated fatty acid?

F. Which lipid molecule is used to store energy in cells such as adipocytes?

G. What does a triglyceride molecule consist of?

H. What type of reaction is involved in the creation of a triglyceride molecule?

I. What reaction is involved in the break-down of a triglyceride molecule?

J. List out all of the different functions of lipids. Make sure you know which class of lipid would be involved in each function.

5.) Amino acids are described as the “building blocks” of which organic macromolecule? Would this be considered a strong or a weak acid? Could it act as a buffer?

A. List and describe the three important components attached to the central carbon of an amino acid.

There are 20 different amino acids in the human body. Go back to your list above and highlight the…
