Which type of chemical reaction is involved in the conversion of polymers to monomers?

Hydrolysis reaction

What type of chemical reaction converts monomers to polymers?

Polymerization reaction

Which of the following is NOT a named example of a polymer?

Amylase (monomer: amino acids)

In the conversion process from polymers to monomers, what role does water play?

Water is added

Which letter in the diagram represents a macromolecule made up of repeating units?

B

Which letter in the diagram represents a simple molecule that is not a polymer?

A

Match the following terms with their definitions:

Monomers = Single units that can join together to form polymers Polymers = Long chains of repeating units formed by the combination of monomers Chemical reactions involved in conversion to monomers = Hydrolysis Chemical reactions involved in conversion to polymers = Dehydration synthesis

Match the following polymers with their associated monomers:

Starch = Glucose Proteins = Amino acids DNA = Nucleotides Cellulose = Glucose

Match the following letters in the diagram with their corresponding molecules:

A = Simple sugar (monosaccharide) B = Amino acid C = Nucleotide D = Fatty acid

Match the following statements with the correct terms:

Role of water in conversion to monomers = Breaking bonds through hydrolysis Role of water in conversion to polymers = Formation of bonds through dehydration synthesis Function of proteins in organisms = Enzymes, structure, and transport Function of DNA in organisms = Genetic information storage and transmission

Match the following biological molecules with their primary function:

Carbohydrates = Short-term energy storage and structural support Lipids = Long-term energy storage and cell membrane structure Proteins = Enzymes, hormones, and immune function Nucleic acids = Genetic information storage and protein synthesis

Match the following terms with their role in biological systems:

Enzymes = Biological catalysts that speed up chemical reactions Hormones = Regulatory molecules that control various physiological processes ATP (Adenosine Triphosphate) = Energy currency of cells used for cellular processes Antibodies = Proteins that help the immune system identify and neutralize pathogens

Test your knowledge on the chemical reactions involved in the conversion of polymers to monomers and vice versa. Identify examples of polymers and their associated monomers to demonstrate your understanding.
