barrier, signaling molecules, and fuel storage, among others - 🧠 ANSWER
✔✔lipids
Cellular organelle where glycosylation occurs. - 🧠 ANSWER ✔✔Golgi apparatus
Organelle that can be 'rough' or 'smooth' and is responsible for protein processing
and
xenobiotic metabolism - 🧠 ANSWER ✔✔endoplasmic reticulum (ER)
Organelle filled with proteases and other digestive enzymes - 🧠 ANSWER
✔✔lysosome
What are the four key classes of biomolecules? - 🧠 ANSWER ✔✔proteins, nucleic
acids (DNA/RNA), carbohydrates, and lipids
How do eukaryotic cells differ from prokaryotic cells? - 🧠 ANSWER

Which biomolecules are chiefly responsible for catalysis of cellular processes? - 🧠
ANSWER ✔✔proteins
DNA and RNA are composed of what basic biochemical compounds? - 🧠
ANSWER ✔✔nucleotides
...weak interaction between water molecules. - 🧠 ANSWER ✔✔hydrogen bonding
Which type of amino acids are responsible for increasing entropy as a protein
folds. - 🧠 ANSWER ✔✔hydrophobic/nonpolar amino acids
Using Coulomb's law, describe how water is an ideal solvent for the ions found in
cells? - 🧠 ANSWER ✔✔Water has a high D, dielectric constant, which makes F
lower. F is the force needed to dissolve ions with charges q1 and q2
What is the significance of hydrogen bonding in biochemical structures such as
DNA? - 🧠 ANSWER ✔✔The weak nature of H bonds (compared to covalent
bonds) allow the two DNA strands to be 'unzipped' during replication, and to
reform again, with less energy
What is an electrostatic interaction? Give an example. - 🧠 ANSWER
✔✔Electrostatic or ionic interactions are between charged groups, or between ions
Like the R groups of Arg and Lys. Or the amino group (-NH3

+) and the carboxyl group (-COO-)
Give another name for van der Waals interactions. - 🧠 ANSWER
✔✔hydrophobic/nonpolar interactions
If most proteins are found surrounded by water in the cell, what type of functional
groups would you expect to
find on the surface of a water soluble protein? - 🧠 ANSWER ✔✔polar/ionic amino
acids
What is the second law of thermodynamics and why does protein folding (which
increases order in the
protein) occur spontaneously? - 🧠 ANSWER ✔✔Entropy of the universe increases
for a spontaneous reaction. Entropy of water used to solvate the nonpolar groups
increase in entropy during protein folding.
How do hydrophobic interactions aid in protein folding? - 🧠 ANSWER
✔✔Hydrophobic interactions exclude water (which increases in entropy).
Hydrophobic groups come together to form a hydrophobic core (for example, of
proteins).
