CLPNA EXAM QUESTIONS WITH
COMPLETE ANSWERS
hydrolysis - Answer-The addition of water that splits apart molecules in reactions.
condensation - Answer-A reaction resulting in the removal of a molecule of water.
starch - Answer-A polysaccharide found in plants; its main role is energy storage.
monomer - Answer-One of many small molecules that combine to form a larger one
known as a polymer.
polymer - Answer-Large molecule made up of repeating smaller molecules (monomers).
monosaccharide - Answer-The monomer unit of carbohydrates.
disaccharide - Answer-A pair of monosaccharides.
polysaccharide - Answer-Formed from many monosaccharides.
cellulose - Answer-A polysaccharide; major component of plant cell walls.
Lipids - Answer-Energy-rich biomolecules made mostly from carbon and hydrogen
atoms
Monomers for Lipids - Answer-Fatty Acids and Glycerol
Elements found in Lipids - Answer-Mostly Carbon (C), Hydrogen (H), and some Oxygen
(O)
Functions of Lipids - Answer-1. long-term energy storage
2. act as structural components of cell membranes
3. provide insulation
Examples of Lipids - Answer-fats, oils, waxes
Fatty Acid Structure - Answer-long hydrocarbon (hydrogen and carbon) chains
Saturated Fats - Answer-Fatty acids that have the maximum number of hydrogen atoms
possible; solid at room temperature; carbon atoms are joined together by a single bond
Unsaturated Fats - Answer-Fatty acids that do not have the maximum number of
hydrogen atoms possible; liquid at room temperature; at least one pair of carbon atoms
is joined by a double bond
