Proteins

What kinds of food can you get protein from in your diet?

• Eggs
• Meat and Fish
• Nuts and Legumes
• All of the above

The bond that joins amino acids are called:

• Peptide Bonds
• Ester Bonds
• Glycosidic Linkages
• Phosphodiester Bonds

The diagram shows a bond forming between two amino acids. What is the name of this reaction?

• Dehydration Synthesis
• Hydrolysis
• Pepysis
• Oxidation

Amino acids all have the same general structure except for the:

• Amino Group
• Carboxyl Group
• 'R' Group
• Carbonyl Group

The reaction used to digest and break the bond in red is:

• Hydrolysis
• Dehydration Synthesis
• Oxidation
• Single Displacement

The primary sequence of a protein refers to the:

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

Structures like an α-Helix are formed because of:

• Hydrophobic Interactions
• DiSulphide Bridges
• Salt Bridges
• Hydrogen Bonding

The number of amino acids used to produce proteins for all living things is:

• 20
• ∞
• 15
• 42

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

• True
• False

What are the building blocks of proteins?

• amino acid
• fatty acid
• nucleotide
• lipid
