Identify the element found in a protein that is not present in a carbohydrate

• Carbon
• Oxygen
• Hydrogen
• Nitrogen

What is a type of protein that speeds up chemical reactions?

• sucrose

• triglyceride

This transport protein is used to move Oxygen throughout the body (to and from red blood cells).  

• hemoglobin
• collagen
• insulin
• antibodies

Which of the following is NOT a function of a protein?

• Storing energy for long periods of time in a small space
• Building structures
• speeding up reactions
• storage 

Which protein structure is matched correctly?

• primary structure : folded amino acid chains due to hydrogen bonds

• secondary structure : interactions between more than one amino acid chain in a protein

• tertiary structure : 3D structure due to interactions of R groups on amino acids

• quaternary structure : chain of amino acids

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
