Chapter 4

Question 1

Bonds that join amino acids together to produce proteins; dehydration synthesis reactions produce dipeptides and polypeptides.

Answer 1

Peptide Bonds

Question 2

The loss of the specific shape of a particular protein, resulting in the loss of its function.

Answer 2

Denaturation

Question 3

Changes in temperature; changes in pH; changes in salt concentration.

Answer 3

Agents of Denaturation

Question 4

The amino acid sequence forming the polypeptide chain.

Answer 4

Primary Structure

Question 5

The overall 3-dimensional shape of the polypeptide.

Answer 5

Tertiary Structure

Question 6

The coiling or folding of the polypeptide chain produced by hydrogen bonding.

Answer 6

Secondary Structure

Question 7

Results from the bonding interactions between the 2 or more polypeptide chains (most proteins become functional at this point)

Answer 7

Quaternary Structure

Question 8

5-carbon sugar; phosphate groupi links sugars by dehydration reactions; nitrogen bases [Adenine, Guanine, Cytosine, Thymine (DNA only); Uracil (RNA only)]

Answer 8

Components of Nucleotide

Question 9

The hereditary material of all living things; instructions for making proteins.

Answer 9

Uses of Nucleic Acids

Question 10
