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

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

The main bonding in the secondary structure of a protein is due to.....

• covalent bonding
• ionic bonding
• hydrogen bonding
• polar bonding

The tertiary structure folding in proteins is primary due to the interactions of....

• the 'R' groups
• the 'P' groups
• the 'A' groups

Our bodies can synthesize some of the essential amino acids we need, but where do we get the ones we cannot synthesize?

• eating animal protein
• taking a supplement
• eating plant protein
• drinking plenty of water

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 entire polypeptide forms a three-dimensional structure

• Primary

• Secondary

• Tertiary

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.
