What are three common entry level jobs for biomedical engineers with a BS degree? (B) Which
of the three sounds most interesting to you? (C) Why? correct answers Product Design Engineer
Quality Engineer
Regulatory Affairs Associate
What is meant by the term "Tissue Engineering"? correct answers The practice of combining
scaffolds, cells, and biologically active molecules into functional tissues.
What is meant by the term "Personalized Medicine"? correct answers The practice of tailoring
medical decisions, practices, interventions and/or products to the individual patient based on
relevant biomarkers from that patient.
How are advances in imaging driving improved healthcare? correct answers Being able to see
inside the body without invasive procedures.
(A) List the most common elements found in the human body and (B) the four classes of
biopolymers that they comprise. correct answers (A) Hydrogen, Oxygen, Nitrogen, Carbon
(B) Polysaccharides, Lipids, Proteins, Nucleic Acids.
(A) List the various subcompartments where water is distributed in the human body and (B) their
approximate percentage of total body water. correct answers Intercellular Fluid (40%)
Extracellular Fluid(20%)
•Interstitial Fluid (Between Cells): 15%
, •Intravascular Fluid: 5%
Approximately 60%.
(A) Using a common set of small molecules as examples explain the difference between polar
and non-polar molecules. (B) Why is polarity important to living systems? correct answers Water
is bonded by polar-covalent bonds which creates a dipole and partial charges on the molecule.'s
elements. Non-polar molecules do not dissolve in polar solutions. Polarity is crucial for life
because it allows for the interaction of non-polar molecules, transportation, and absorption of
different nutrients.
What is meant by the term "polymer". correct answers Many Parts. A macromolecule. Network
of entangled or cross-linked chains of repeating monomers.
(A) List the four major types of biological polymers (biopolymers) and (B) provide a simple
chemical or structural representation of each. correct answers Lipids, polysaccharides, nucleic
acids, and proteins.
see cards.
Describe what is meant by the term "condensation reaction" and provide an example. correct
answers Water is produced.
(A) What is a polysaccharide? (B) Where are they commonly found in the human body? (C)
What role(s) do they serve? correct answers A sugar or a carbohydrate. In glucose which stores
energy for the body to use.
What is the general chemical structure of a lipid molecule? correct answers Hydrophilic head.
Hydrophobic tail.
What molecules are found in all cell membranes and how are they organized, that is, which end
of the molecule faces the extracellular fluid (ECF) and which end is buried inside the bilayer?
correct answers Cell membrane is is made up of a phospholipid bilayer. Fatty Acids (lipids)
make up this bilayer by situaing their hydrophobic tails buried inside and their hydrophobic
heads outside able to interact.
Describe two roles of cell membranes correct answers Permeability to small molecules.
Protection to the cell.
What is the difference between an unsaturated, cis-saturated, and trans saturated lipid. Which is
considered unsafe? correct answers Unsaturated- it tends to be liquid at room temperature and,
has a cis- double bond configuration.
Saturated- Solid at room temperature. No double bonds.
Trans-double bonded.
Unsafe - Transfat.
