3.2 & 3.3 Study Guide

Question 1

Monomers and Polymers

Answer 1

Monosaccharides, Fatty Acids, Amino Acids, Nucleic Tides, Polysaccharides, Triglycerides, Polypeptides, Polynucleotides.

Question 2

Functions of the macromolecules.

Answer 2

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

Question 3

Similarities and differences in amino acid structures.

Answer 3

The α 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

Primary, secondary, tertiary, and quaternary structure.

Question 5

What happens during protein denaturation?

Answer 5

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

Can disrupt the protein’s structure and function.
