task 2 - molecules of life tutorial
use any method to complete the molecules of life tutorial from the cpalms website. as you complete the tutorial, answer the following questions. tiny url: http://tinyurl.com/zvl86qb

1. how is a train comparable to a macromolecule?
2. summarize the meanings of the following prefixes:

a. micro:
c. mono:
b. macro:
d. poly:

1. differentiate between a monomer and polymer.
2. fill in the blank. a train - car is to a train as a _ is to a polymer and a molecule is to a _.
3. list the 4 classes of macromolecules.
4. what are two important functions of carbohydrates?
5. what type of complex carbohydrate is cellulose and what is its role in plant cells?
6. what is another name for a complex carbohydrate?

Explanation:

1. Biomolecules are molecules present in living organisms.
2. Carbohydrates are a source of energy.
3. The monomer of carbohydrates is a monosaccharide.
4. Lipids are also known as fats.
5. Three functions of lipids are energy - storage, insulation, and forming cell membranes.
6. After running out of carbohydrate energy, the body gets more energy from lipids.
7. The monomers of proteins are amino acids.
8. Three functions of proteins are building tissues, acting as enzymes, and transporting substances.
9. Enzymes are made of proteins.
10. Two examples of nucleic acids are DNA and RNA.
11. DNA and RNA code for proteins.
12. The monomer of nucleic acids is a nucleotide.
13. a) Carbohydrates: Carbon, Hydrogen, Oxygen; b) Lipids: Carbon, Hydrogen, Oxygen; c) Protein: Carbon, Hydrogen, Oxygen, Nitrogen (and sometimes Sulfur); d) Nucleic Acids: Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus.
14. A train is made up of multiple train - cars linked together, similar to how a macromolecule is made up of multiple monomers linked together.
15. a) micro: small; b) macro: large; c) mono: one; d) poly: many.
16. A monomer is a single unit, while a polymer is a long chain made up of many monomers linked together.
17. A train - car is to a train as a monomer is to a polymer and a molecule is to a macromolecule.
18. The 4 classes of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
19. Two important functions of carbohydrates are providing energy and structural support.
20. Cellulose is a polysaccharide (complex carbohydrate). Its role in plant cells is to provide structural support to the cell wall.
21. Another name for a complex carbohydrate is a polysaccharide.
