Macromolecules Mini Project

Today in class students had time to work on their Macromolecules Mini Project.  You do need to have a bibliography for this project.  Please use the MLA format for your bibliography.  EasyBib is a great resource for helping make a bibliography.

In case you 'misplace' the expectations for the project, you can read the guidelines below.

Part 1: Create a poster with the following information for your macromolecule: The name of macromolecule Provide a short description of the macromolecule’s functions in the cell and in our bodies. At least three large, colorful, labeled images of the macromolecule should be on the poster.

Part 2: Create a one- page handout for the class that answers the questions listed under your macromolecule (or protein shape). The handout does not need to be typed, it can be hand written. Keep in mind that this will be photocopied and given to the rest of the class.

This mini project is due on Tuesday September 27th in class. One representative from the group will share the information on your topic with the class.

1. What defines a carbohydrate and what is its function in both plant and animal cells?
2. Monosaccharides (-oses), the ratio of C:H:O
3. Disaccharides: reaction used to join them, removal of water, sucrose, maltose and lactose.
4. Polysaccharides: starches (glycogen; cellulose) 
5. What are the main uses of carbohydrates in cells (plants and animals)?

1. Define lipids—insolubility in water; function.
2. Types of lipids—triglycerides, phospholipids, steroids
3. What are the main uses of lipids in cells

1. Define proteins and their function
2. What is an amino acid (monomers joined via dehydration synthesis)
3. How is a Peptide bond formed?
4. What are the main uses of proteins in cells?

Protein Shape:
1. What are the various levels in protein shape? (primary, secondary, tertiary, quaternary)
2. How does structure relate to function with regard to proteins?
3. What does it mean to denature a protein, give an example.

Nucleic Acids: 
 1. Define, compare and give examples of the two types of nucleic acids (structure, location and function).
2. What are the main uses of nucleic acids in cells?
