BMS 300 EXAM 1 COLORADO STATE
EXAM QUESTIONS AND CORRECT
ANSWERS
\.Electric Dipole Moment - ANSWERS✔-Neutral molecule with uneven charge
distributions (partial charges) e.g. H2O
\.Diffusion - ANSWERS✔-Movement of molecules from areas of high to low
concentrations e.g. Volatile Perfume distributing through the air
\.Osmosis - ANSWERS✔-Diffusion of WATER through a membrane e.g. Aquaporins
(biological proteins)
\.Hydrophilicity - ANSWERS✔-"Water Loving" e.g. Charged ions that interact with
the Electric Dipole Moment in water. (Soluble)
\.Hydrophobicity - ANSWERS✔-"Water Fearing" e.g. molecules with equal
distribution of charge such as Triglycerides (Insoluble)
\.Amphipathicity - ANSWERS✔-Both Water "Fearing and Loving" e.g.
Phospholipids in water
, \.Glycerol - ANSWERS✔-3 Carbon Alcohol (OH)
\.Triglycerides - ANSWERS✔-3 Fatty Acid Chains on Glycerol formed by Ester Bonds
\.Ester Bond - ANSWERS✔-Created from Dehydration Synthesis to make a C-O-C
bond in Triglycerides (Leaves Behind a Water Molecule)
\.Dehydration Synthesis - ANSWERS✔-Carboxylic end of Fatty Acid Chain attaches
to Glycerol to create an Ester Bond and Water Molecule
\.Fatty Acids - ANSWERS✔-Saturated-Single bond
Unsaturated-Double bond
\.Phospholipid - ANSWERS✔-Remove a fatty acid chain and add a charged
phosphate head group to make it Amphipathic
\.Micelle - ANSWERS✔-Single layer of UNSTABLE phospholipids (Due to Dipole
Moment)
\.Phospholipid Bi-layer - ANSWERS✔-STABLE formation of Phospholipids
\.Transmembrane Protein - ANSWERS✔-Provide pathways across the Phospholipid
Bi-layer
