Sample Questions

Question 1
Which physicochemical property of water allows humans and other mammals to release excess body heat effectively during sweating?
High heat of vaporization resulting from extensive intermolecular hydrogen bonding.
Low boiling point caused by nonpolar covalent bonds within the water molecule.
High density in the solid phase compared to the liquid phase.
Low surface tension facilitating rapid hydrophobic evaporation.
Question 2
What happens to human red blood cells (erythrocytes) when placed in a hypertonic sodium chloride solution?
Water moves out of the cells by osmosis, causing them to shrink and undergo crenation.
Water enters the cells by osmosis until they swell and burst in a process called hemolysis.
Sodium ions rapidly diffuse into the cells by simple diffusion, causing cell swelling.
The cells maintain a constant volume because the plasma membrane is impermeable to water.
Question 3
Which structural feature distinguishes D-glucose from D-fructose?
D-glucose is an aldohexose with a carbonyl group at C1, whereas D-fructose is a ketohexose with a carbonyl group at C2.
D-glucose is a pentose sugar found in RNA, whereas D-fructose is a hexose sugar found in plant cell walls.
D-glucose contains beta-1,4-glycosidic linkages, whereas D-fructose contains alpha-1,4-glycosidic linkages.
glucose is a non-reducing sugar, whereas D-fructose cannot undergo ring closure in aqueous solution.
Question 4
Which chemical reaction forms a triglyceride (triacylglycerol) from glycerol and fatty acid molecules?
Esterification of three fatty acid carboxyl groups with three glycerol hydroxyl groups, releasing three water molecules.
Hydrolysis of peptide bonds between amino acid residues in the presence of acidic catalysts.
Condensation of three phosphate groups with the nitrogenous base adenosine to form high-energy bonds.
Hydrogenation of unsaturated carbon-carbon double bonds to produce branched sphingolipids.
Question 5
Which functional groups react during the formation of a peptide bond between two amino acids?
The alpha-carboxyl group of one amino acid and the alpha-amino group of another amino acid.
The variable R-group side chain of a hydrophobic amino acid and a phosphate group.
The hydroxyl group of a serine residue and the methyl group of an alanine residue.
The aldehyde group of a reduced sugar and the imidazole ring of a histidine residue.
