Macromolecules, Membranes, and Transport Practice Test KEY
Macromolecules:
The process that joins monomers into polymers and produces water is: Dehydration
The process that breaks up polymers into monomers and uses water is: Hydrolysis
Match the monomer with the polymer AND with its function:
G,B
monosaccharide
E,D
triglyceride
C,F
amino acid
A,H
nucleotide
A. nucleic acid
B. energy and structure
C. protein
D. long term energy, structure, insulation
E. lipid
F. enzymes and structure
G. carbohydrate
H. genetic material and Information transfer

Cell Membrane:
Draw a phospholipid bilayer with AT LEAST ten phospho-lipids. Label the phosphate-group, fatty acid
tails, and the hydrophilic and hydrophobic parts. Draw an active transport membrane protein. Draw
and label the atoms/molecules that are being transported (make sure you correctly illustrate the
correct high and low concentrations for these molecules).
Refer to your active transfer diagram in your notes
Functions of the cell membrane:
Keeping internal chemical conditions stable with in a cell is called: Homeostasis
