B1.1.2-3

Question 1

Define monomer

Answer 1

A single unit or building block (e.g., glucose for starch).

Question 2

Define polymer

Answer 2

A long chain of repeating monomers (e.g., starch is a polymer of glucose).

Question 3

Describe condensation reactions.

Answer 3

A chemical reaction where two molecules combine to form a larger molecule, releasing a molecule of water.

Question 4

State that energy from ATP is needed to produce macromolecules by condensation reactions.

Answer 4

ATP provides the energy required for condensation reactions to form macromolecules.

Question 5

Outline the condensation reactions that form polysaccharides

Answer 5

Glucose monomers condense to form starch or cellulose.

Question 6

Outline the condensation reactions that form Polypeptides:

Answer 6

Amino acids condense to form proteins.

Question 7

Outline the condensation reactions that form Nucleic Acids

Answer 7

Nucleotides condense to form DNA or RNA

Question 8

Describe hydrolysis reactions.

Answer 8

A reaction in which water is added to break down a polymer into its monomers (opposite of condensation).

Question 9

Outline the hydrolysis reactions that digest polysaccharides

Answer 9

Starch is hydrolyzed to release glucose.

Question 10

Outline the hydrolysis reactions that digest Polypeptides

Answer 10

Proteins are hydrolyzed to amino acids.

Question 11

Outline the hydrolysis reactions that digest Nucleic Acids:

Answer 11

DNA or RNA is hydrolyzed to release nucleotides
