3.2 and 3.3 SG

Question 1

The monomer and polymer names for each macromolecule group.

Answer 1

Carbohydrate: Monosaccharides
Lipids: Fatty Acids
Proteins: Amino Acids
Nucleic Acids: Nucleotides

Question 2

The functions of each macromolecule group.

Answer 2

Proteins – Molecular Machines.
Nucleic Acids – Information Repositories.
Lipids – Waterproof Membranes.
Carbohydrates – Stored Energy.

Question 3

Similarities and differences in amino acid structure.

Answer 3

The carbon, carboxyl, and amino groups are common to all amino acids, so the R-group is the only unique feature in each amino acid

Question 4

The four levels of protein structure.

Answer 4

The four levels of protein structure are primary, secondary, tertiary, and quaternary.

Question 5

What happens during protein denaturation?

Answer 5

During the denaturation of proteins, the secondary and tertiary structures get destroyed and only the primary structure is retained.

Question 6

Why and how would the structure and function of a protein change if a hydrophobic amino acid was substituted for a hydrophilic one?

Answer 6

A protein’s structure and function are closely linked, so changes in structure due to a single amino acid substitution can affect the protein’s function.
