BMS 300 Exam 1 (Colorado State
University) questions with answers
Dipole Moment - ** VERIFIED ANSWERS **✔✔The difference in charge between atoms in a water
molecule
Water Molecules Interact With Each Other Through _______ - ** VERIFIED ANSWERS
**✔✔Hydrogen Bonds
Why is water liquid at room temperature? - ** VERIFIED ANSWERS **✔✔Because the hydrogen
bonds within it are constantly breaking and reforming on different molecules (moving around)
Shell of Hydration - ** VERIFIED ANSWERS **✔✔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 - ** VERIFIED ANSWERS **✔✔The movement of water through aquaporins
Aquaporins - ** VERIFIED ANSWERS **✔✔Water-Selective Channels
How do plants and trees move water upwards from the ground? - ** VERIFIED ANSWERS
**✔✔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 - ** VERIFIED ANSWERS **✔✔-animal fats or vegetable oils
-Hydrophobic, water insoluble
Ester Bond - ** VERIFIED ANSWERS **✔✔Happens when a fatty acid and a glycerol molecule bond
, Are Phospholipids Amphipathic? - ** VERIFIED ANSWERS **✔✔Yes. They have hydrophobic
regions and hydrophilic regions
Micelle - ** VERIFIED ANSWERS **✔✔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 - ** VERIFIED ANSWERS **✔✔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? - ** VERIFIED ANSWERS **✔✔Through hydrophilic
protein channels
What are the components of an amino acid? - ** VERIFIED ANSWERS **✔✔-Amino Group
-Carboxcylic Acid
-Distinguishing R-group
What kind of bond forms within amino acids? - ** VERIFIED ANSWERS **✔✔Peptide Bonds
What are the two ends of an amino acid? - ** VERIFIED ANSWERS **✔✔Aminoterminus and
Carboxyterminus
What is Primary Protein Structure and what kind of bond is associated with it? - ** VERIFIED
ANSWERS **✔✔Amino Acid Chains, Peptide Bonds
What is Secondary Protein Structure and what kind of bond is associated with it? - ** VERIFIED
ANSWERS **✔✔Alpha Helix and Beta Pleated Sheets, Hydrogen Bonds
What does the "i+4" rule refer to? - ** VERIFIED ANSWERS **✔✔The positively charged part of the
amine hydrogen interacts with the negatively charged carbonyl oxygen *five up the line* in alpha
helix structure (through hydrogen bonding)
