Monomers
are joined together through
condensation
reactions to form larger
polymer
molecules.
Polymers are large molecules made up of repeating
monomers
Monomers
are the
basic
units
or
building
blocks
that make up
polymers
Monomers are large, complex molecules
False
Condensation reactions in polymers involve the
removal
of
water
molecules
Polymerization
is the process of forming polymers from
monomers
Monomers are the basic units that make up
polymers
Monomers are
small
, simple molecules
True
What are monomers defined as?
Basic units of polymers
Polymers are large molecules made of repeating monomers joined by
condensation
Polymers
are formed through
condensation
reactions with the removal of water
molecules.
True
What type of monomers form proteins?
Amino acids
Polymers are small, simple molecules.
False
Which monosaccharide forms carbohydrates?
Glucose
Proteins are polymers formed from amino acid
monomers
What is the primary function of carbohydrates in the body?
Energy storage
Polymers are formed through dehydration reactions
True
Match the polymer with its monomer:
Proteins ↔️ Amino acids
Carbohydrates ↔️ Monosaccharides
Nucleic acids ↔️ Nucleotides
Polymers are formed by joining monomers together through
condensation
reactions.
Polymers
are formed through
condensation reactions
True
Monomers can undergo condensation reactions to form
polymers
.
True
What are polymers made of?
Repeating units of monomers
Steps involved in polymerization
1️⃣ Condensation reactions join monomers
2️⃣ Water molecules are removed
3️⃣ Polymers are formed
Polymerization involves condensation reactions and the removal of water
molecules
Match the monomers with their corresponding polymers:
Amino acids ↔️ Proteins
Monosaccharides ↔️ Carbohydrates
Nucleotides ↔️ Nucleic acids
What type of monomers form carbohydrates?
Monosaccharides
Proteins have a complex
3D
structure formed by chains of
amino
acids.
True
Match the polymer with its function:
Proteins ↔️ Enzymes, antibodies
Carbohydrates ↔️ Energy storage
Nucleic acids ↔️ Genetic information
