What is the process by which monomers are linked together to form polymers?
a. protein formation
b. coiling
c. monomerization
d. dehydration reaction
e. hydrolysis - Answer-dehydration reaction
When monomers are linked together to form a more complex polymer, a water molecule
is removed by dehydration reactions.
In a hydrolysis reaction, __________, and in this process water is __________.
a. monomers are assembled to produce a polymer ... produced
b. a monomer is broken up into its constituent polymers ... produced
c. a polymer is broken up into its constituent monomers ... consumed
d. monomers are assembled to produce a polymer ... consumed
e. a polymer is broken up into its constituent monomers ... produced - Answer-a
polymer is broken up into its constituent monomers ... consumed
The meaning of hydrolysis is "to break with water."
The type of bond that forms to join monomers (such as sugars and amino acids) into
polymers (such as starch and proteins) is a(n) __________ bond.
a. covalent
b. van der Waals
c. hydrogen
d. peptide
e. ionic - Answer-covalent
Monomers are joined together by a dehydration reaction in which two molecules are
covalently bonded to each other through the loss of a water molecule.
Which of the following is a polymer?
a. triacylglycerol, or fat
, b. fructose, a component of sucrose
c. glucose, an energy-rich molecule
d. testosterone, a steroid hormone
e. cellulose, a plant cell wall component - Answer-cellulose, a plant cell wall component
The polysaccharide cellulose is a major component of plant cell walls. It is a polymer
composed of many glucose monomers joined together by glycosidic linkages.
Cellulose is a __________ made of many __________.
a. protein ... amino acids
b. lipid ... triacylglycerols
c. polypeptide ... monomers
d. polymer ... glucose molecules
e. carbohydrate ... fatty acids - Answer-polymer ... glucose molecules
Cellulose is a polysaccharide and therefore a polymer, constructed from many
monosaccharide glucose monomers.
Generally, animals cannot digest (hydrolyze) the glycosidic linkages between the
glucose molecules in cellulose. How then do cows get enough nutrients from eating
grass?
a. They have to eat a lot of grass.
b. Cows and other herbivores are exceptions and make some cellulose-digesting
enzymes.
c. Microorganisms in their digestive tracts hydrolyze the cellulose to individual glucose
units.
d. The flat teeth and strong stomach of herbivores break the cellulose fibers so that the
cows get enough nutrition from the cell contents.
e. All of the listed responses are correct. - Answer-Microorganisms in their digestive
tracts hydrolyze the cellulose to individual glucose units.
Cows have digestive chambers populated by microorganisms that can produce certain
hydrolytic enzymes that cows cannot. The enzymes hydrolyze (digest) the cellulose
polymer into glucose monomers.
In what polysaccharide form do plants store glucose to be available later as an energy
source?
a. protein
b. starch
c. fatty acids
d. cellulose
e. glycogen - Answer-starch
Starch is a glucose storage polymer in plants.
