28 anatomy & physiology coloring workbook

1. the biochemical reaction shown in figure 2 - 6 represents the complete digestion of a polymer (a large molecule as consumed in food) down to its constituent monomers, or building blocks.

(a) select two colors and color the coding circles and the molecules.
(b) select the one correct answer for each statement below and insert your answer in the answer blank.
monomer polymer
figure 2 - 6

1. if starch is the polymer, the monomer is:

a. glycogen. b. amino acid. c. glucose. d. maltose.

1. during polymer digestion, water as h+ and oh - ions would

a. be a product of the reaction.
b. act as a catalyst.
c. enter between monomers, bond to them, and keep them separated.
d. not be involved in this reaction.

1. another name for the chemical digestion of polymers is:

a. dehydration. b. hydrolysis. c. synthesis. d. displacement.

1. if the monomers are amino acids, they may differ from each other by their:

a. r group. b. amino group. c. acid group. d. peptide bond.

Explanation:

Step1: Recall starch monomer

Starch is a polymer of glucose.

Step2: Analyze water role in digestion

In polymer digestion (hydrolysis), water splits polymers into monomers by adding across bonds.

Step3: Know polymer digestion name

Chemical digestion of polymers is hydrolysis.

Step4: Recall amino - acid structure

Amino acids differ by R - group.

Answer:

1. C. glucose
2. C. enter between monomers, bond to them, and keep them separated
3. B. hydrolysis
4. A. R group
