QUESTIONS
Question 1
Proteins are made out of:
- Fatty acids
- Amino acids
- Carbohydrates
- Lipids
Question 2
Which of the following is a protein based structure?
- Fatty esters
- Glycogen
- Starch
- Enzymes
Question 3
Drag the descriptions into the appropriate structure column.
- Primary
- Secondary
- Tertiary
- Quaternary
Question 4
In this lesson, we have studied how amino acids are able to form complex polymers. We see that these amino acids can link together to form polypeptides and proteins, each with unique structures and functions.
In the next section you will probe your understanding of proteins through a series of questions. Prior to completing this, let us take a moment to review the four classes of biomolecules we studied with the activity here.
Drag the descriptions to the appropriate biomolecule class.
Question 5
If two amino acids are combined with a peptide bod, how would you describe the structure?
- Polypeptides
- Amide
- Dipeptide
- Protein
Question 6
The primary structure of a protein consists of;
- The three-dimensional structure of a protein arising from disulfide linkages, salt bridges, hydrogen, and dispersion forces.
- The interaction between more than one chain of protein
- A chain of amino acids combined together through peptide bonds
- The local hydrogen bonding interactions between nearby amino acids.
Question 7
An enzyme is best described as a;
- Antibody
- Biological catalyst
- Hormone
- Energy source
Question 8
Which of the following statements regarding amino acids are correct? Select all that apply.
- All amino acids have both a carboxylic acid and an amine group
- Proteins are 2 or more amino acids linked together.
- Amino acids form polypeptides sequences through peptide bonds
- Essential amino acids cannot be synthesized by the body.
Question 9
If I were to cool down an enzyme found in the human body to about 5 degrees Fahrenheit, I would expect;
- The activity of the enzymes to decrease
- The enzyme to break down into amino acids
- The substrate to change
- The activity of the enzyme to increase

- Triglycerides
- Starch
- Insulin
- Actin
