Unit #2.1: Chemistry of Life/Macromolecules and Enzymes
Quarter 1
Approximate
Time:
8 days
Unit Overview
All living things are composed of four basic categories of macromolecules and share the same basic needs for life. Students need to relate the primary
function of the carbohydrates to providing and storing energy. Also, students will relate the primary function of lipids to insulating, energy storage, and
cell membrane make up and relate the primary function of nucleic acids (DNA and RNA) to cellular control by directing protein synthesis. Students will
also need to identify enzymes as biological catalysts and explain the “lock and key” model as it relates to enzyme activity. Also, they will explain the
effect of a catalyst on activation energy.
Learning Goal
Sample Essential Questions
Students will be able to:
 Students will identify and/or describe the basic molecular
structure of carbohydrates, lipids, proteins, and/or nucleic acids,
and describe the primary functions of macromolecules in
organisms.
 Students will explain how enzymes speed up the rate of a
biochemical reaction by lowering the reaction’s activation
energy. Students will identify and/or describe the effect of
environmental factors on enzyme activity.
Learning Scale Unit 2.1


How do the macromolecules of life differ from one another in structure
and in function?
Why are enzymes important and how do they work?
Honors:
 Differentiate between monosaccharides, disaccharides and polysaccharides.
 What are the functions of carbohydrates in living things?
 What evidence do you have that show the relationship between the structure and
function of enzymes?
Focus Standards
SC.912.L.18.1: Describe the basic molecular structures and primary functions of the four major categories of biological macromolecules.
SC.912.L.18.11: Explain the role of enzymes as catalysts that lower the activation energy of biochemical reactions. Identify factors, such as pH and
temperature
Honors:
SC.912.L.18.2 - Describe the important structural characteristics of monosaccharides, disaccharides, and polysaccharides and explain the functions of carbohydrates in living things.
SC.912.L.18.3 - Describe the structures of fatty acids, triglycerides, phospholipids, and steroids. Explain the functions of lipids in living organisms. Identify some reactions that fatty acids
undergo. Relate the structure and function of cell membranes.
SC.912.L.18.4 - Describe the structures of proteins and amino acids. Explain the functions of proteins in living organisms. Identify some reactions that amino acids undergo. Relate the
structure and function of enzymes.
Unit End Product or Teaching Task
Students will complete a written lab report for this unit, using what they have learned about macromolecules and the effect of enzymes on chemical reactions.

Macromolecule Food Indicator Lab - students will complete a lab using
indicators to determine which foods contain carbohydrates, lipids,
proteins, and/or starches. The lab includes pre-lab questions,
discussion, lab experimentation, post lab questions, results and
conclusion.

Enzymes in Action (5E lesson) - Students will predict, investigate,
observe, and report on the effects that pH, concentration, and
temperature have on catalase enzyme reactions. Students will conduct
an experiment in which they will alter the pH, concentration, and
temperature of the environment in which catalase enzyme reactions
are taking place. Students will be able to describe how changes in
these environmental conditions affect the action of the enzymes in
living things.
Honors:
Got Lactase? - Students to observe and identify evidence of an enzyme's
activity, lactase, and its function, and action on a substrate found in milk,
lactose.
