First, polymers are long chains which are made up of
many molecules known as monomers. These can be
anything from amino acids, to alkenes, to alcohols. What
all polymers have in common is the type of bond which
holds their monomers together. What type of bond is
this? Ans: A covalent bond
True or False? The type of chemical reaction responsible
for linking monomers into polymers is known as
condensation (or dehydration) reaction. Ans: True
What is lost when two monomers undergo a
condensation reaction? Ans: Water
Actin and myosin are proteins that perform what
function? Ans: Allow for movement as they are major
components of muscle tissue
Hemoglobin is a protein that performs what function?
Ans: Allow for transport of oxygen through the blood
stream
Proteins are polymers made up of monomers known as
Ans: Amino acids
Which of the following depicts a monomer of proteins?
Ans: A
