BMS 300 Exam 1 | Newest Questions and
Answers | 2026 Update | Expert Verified
• Diffusion -✓✓ Movement of molecules from areas of high to low concentrations
e.g. Volatile Perfume distributing through the air
• Osmosis -✓✓ Diffusion of WATER through a membrane e.g. Aquaporins
(biological proteins)
• Hydrophilicity -✓✓ "Water Loving" e.g. Charged ions that interact with the
Electric Dipole Moment in water. (Soluble)
• Hydrophobicity -✓✓ "Water Fearing" e.g. molecules with equal distribution of
charge such as Triglycerides (Insoluble)
• Amphipathicity -✓✓ Both Water "Fearing and Loving" e.g. Phospholipids in
water
• Glycerol -✓✓ 3 Carbon Alcohol (OH)
• Triglycerides -✓✓ 3 Fatty Acid Chains on Glycerol formed by Ester Bonds
• Ester Bond -✓✓ Created from Dehydration Synthesis to make a C-O-C bond in
Triglycerides (Leaves Behind a Water Molecule)
• Dehydration Synthesis -✓✓ Carboxylic end of Fatty Acid Chain attaches to
Glycerol to create an Ester Bond and Water Molecule
, • Fatty Acids -✓✓ Saturated-Single bond
Unsaturated-Double bond
• Phospholipid -✓✓ Remove a fatty acid chain and add a charged phosphate head
group to make it Amphipathic
• Micelle -✓✓ Single layer of UNSTABLE phospholipids (Due to Dipole Moment)
• Phospholipid Bi-layer -✓✓ STABLE formation of Phospholipids
• Transmembrane Protein -✓✓ Provide pathways across the Phospholipid Bi-layer
• Amino Acid -✓✓ Molecule with Amine(NH2), Carboxylic(COOH), and an R
group(20 varieties)
• Protein -✓✓ Polymers of Amino Acids
• Peptide Bonds -✓✓ Connecting N-terminus and C-terminus of Amino Acid
through Dehydration synthesis to create C-N bond
• Primary Structure -✓✓ Determined by Peptide Bonds and the Amino Acid
Sequence
• Secondary Structure -✓✓ Hydrogen Bonding of the two terminals can create
Alpha Helices and Beta Pleated Sheets
