BIOA01H3 Chapter : Lecture 3

11 - Can you distinguish carboxylic acid, amino, and phosphate functional groups?

12- The 4 major types of macromolecules found in living cells are: carbohydrates, lipids, proteins, nucleic acids.

13- What distinguishes a monomer from a polymer. What are the monomer subunits that are used to produce the different types of macromolecules.

14- What is the general formula for a carbohydrate.

15- What are biologically important kinds of lipids. Why are these molecules important.

16- The monomer building block of a protein is an amino acid. What is the basic structure of an amino acid.

17- A nucleotide (the monomer building block of a nucleic acid) is comprised of a nitrogen base, a pentose (5C) sugar, and at least one phosphate.

18- What is the complete name for the nitrogen bases commonly referred to as A, G , C, T, and U. Which are purines? Which are pyrimidines?

19- What is the significance ATP?

20- Generally speaking, what are the functions of the different types of macromolecules.

For the 4 groups of macromolecules give the purpose/function, the monomer (building block unit), and some example polymers (complex unit of 3+ monomers).

- Carbohydrates

- Lipids

-Proteins

-Nucleic Acid

For each category of macro molecules: carbohydrates, lipids,protein and nucleic acid.Select a representative polymer and express its function within the cell.
Suggest which aspect of ur chosen molecules are characteristics of class of macro molecules to which it belongs by identifying it's monomers subunits and describing their basic characteristics structure and the manner in which the monomers are linked together.
