1.4 Protein Folding

What is a peptide bond?

• Bond that holds two amino acids together.
• A bond that holds hydrogen and oxygen molecules together.
• A bond that holds the phosphate group of one nucleotide and a sugar of a neighboring nucleotide.
• A bond that is formed by the sharing of electrons.

The structure of proteins can be changed by environmental factors such as temperature or pH.

• True
• False

When a protein unfolds, it is

• Denatured
• Building
• Adding amino acids
• Making food

The primary sequence of a protein refers to the:

• Order of amino acids
• α-Helix or β-Pleated Sheet
• Interaction of subunits
• Hydrogen Bonding

How many structures or stages are there in proteins?

• 1
• 2
• 3
• 4

The two types of folding in the secondary structure are.....

• alpha-helix & beta-pleated sheets
• polypeptide & nucleotide
• globular & fibrous

What gives a protein its unique shape?

• the unique sequence of amino acids in its polypeptide chain
• the unique folding due to the sequence of amnio acids in the polypeptide chain
• hydrogen bonding & unique interactions between the 'R' groups
• all of these

The name of the initial chain of monomers in a protein is called.....

• polypeptide
• polysaccharide
• polyester
• polynucleotide
