BMS 300 Exam 1 (Colorado State
University) correctly answered to pass

Dipole Moment - correct answer ✔✔The difference in charge between atoms in a water
molecule
Water Molecules Interact With Each Other Through _______ - correct answer ✔✔Hydrogen
Bonds
Why is water liquid at room temperature? - correct answer ✔✔Because the hydrogen bonds
within it are constantly breaking and reforming on different molecules (moving around)
Shell of Hydration - correct answer ✔✔The oxygen atoms in water will orient themselves
towards positively charged ions in water, the hydrogen atoms will orient themselves towards
negatively charged ions in water
Osmosis - correct answer ✔✔The movement of water through aquaporins
Aquaporins - correct answer ✔✔Water-Selective Channels
How do plants and trees move water upwards from the ground? - correct answer ✔✔Water will
move across a barrier if one side has more ions than the other. If aquaporins allow water to
move but not ions, water will continuously flow towards the other side and drain from the
other, causing hydrostatic pressure to form and water to move upwards.
Triglycerides - correct answer ✔✔-animal fats or vegetable oils
, -Hydrophobic, water insoluble
Ester Bond - correct answer ✔✔Happens when a fatty acid and a glycerol molecule bond
Are Phospholipids Amphipathic? - correct answer ✔✔Yes. They have hydrophobic regions and
hydrophilic regions
Micelle - correct answer ✔✔A sphere of phospholipids with hydrophobic tails on the inside and
hydrophilic heads on the outside. If any water enters a micelle, it will explode.
Liposome - correct answer ✔✔a sphere with a phospholipid bilayer. Hydrophobic tails face
towards each other inside the outer layer of hydrophilic heads. This is a more stable structure as
water entering it will not destroy it.
How do proteins move in and out of cells? - correct answer ✔✔Through hydrophilic protein
channels
What are the components of an amino acid? - correct answer ✔✔-Amino Group
-Carboxcylic Acid
-Distinguishing R-group
What kind of bond forms within amino acids? - correct answer ✔✔Peptide Bonds
What are the two ends of an amino acid? - correct answer ✔✔Aminoterminus and
Carboxyterminus
What is Primary Protein Structure and what kind of bond is associated with it? - correct answer
✔✔Amino Acid Chains, Peptide Bonds
