Macromolecule Stations
We ALL start here:
Block: ____
Do Now: What is the importance of knowing that a large percentage of
our body is made of C, H, O, and N? How does this knowledge impact
our daily lives?
Brainstorming: Explain/conclude what do you think may be happening to
the proteins in the frying egg? Use you prior knowledge to answer to the
best of your ability. Hint: think about “homeostasis”
Carbon Compounds- Close Reading/ Annotate:
Organic chemistry is the study of all compounds
that contain bonds between carbon
atoms. Carbon compounds are also called
organic compounds. Many of the molecules
in living things are so large that they are
known as macromolecules. Macromolecules
are formed in a process called polymerization.
Smaller units, called monomers, join together
to form macromolecules, or polymers.
Four groups of organic compounds
found in living things are carbohydrates,
lipids, nucleic acids, and proteins. Carbohydrates
are compounds made up of carbon,
hydrogen, and oxygen atoms. Living things
use carbohydrates as their main source of
energy. Plants and some animals use carbohydrates
in structures. Starches and sugars
are examples of carbohydrates.
Lipids are made mostly from carbon and
hydrogen atoms. Fats, oils, and waxes are
lipids. Lipids are used in living things to
store energy. Some lipids are important parts
of biological membranes and waterproof
coverings. Lipid molecules are made up of
compounds called fatty acids and glycerol.
Nucleic acids contain hydrogen, oxygen,
nitrogen, carbon, and phosphorus.
Nucleotides are the monomers that make
up nucleic acids. Each nucleotide consists of
a 5-carbon sugar, a phosphate group, and a
nitrogenous base. Nucleic acids store and
transmit hereditary, or genetic, information.
There are two kinds of nucleic acids:
ribonucleic acid (RNA) and deoxyribonucleic
acid (DNA).
Proteins contain nitrogen as well as carbon,
hydrogen, and oxygen. Proteins are
polymers of molecules called amino acids.
Some proteins control the rate of reactions
and regulate cell processes. Some are used

to form bones and muscles. Others transport
substances into or out of cells or
help to fight disease.

Biochemistry Stations
Pick your station……
Directions: Review the information below. Pick the station you are
comfortable with and begin your challenge. Complete the worksheets in
the station of your choice.
Station 1: Organic Molecules Worksheet – Independent Discovery!
This station requires the application of your knowledge of
macromolecules as well as an introduction to macromolecules not yet
discussed in class. You are expected to read the worksheet and apply
past biology knowledge to discover new biology concepts at a higher level
of understanding of macromolecules.
Station 2: Elements and Macromolecules in Organisms – Deeper
Understanding using more “visuals”
This station allows you to review macromolecules at a deeper level.
In addition it helps you to visualize the molecules in a structured format
different than what was done in class. This station introduces new
macromolecules in the same manner. You are expected to take your
prior knowledge as well as the new knowledge learned from the packet to
uncover the properties and function of macromolecules not yet
discussed in class.
Station 3: Organic Molecules Worksheet – Getting Down to the Basics –
Independent Research
This station requires you to search independently to discover and
review macromolecules. You are expected to use any resource you are
comfortable with. Independent research will help you to know how to
become more resourceful as well as be able to identify important facts.
This is an important skill to develop to further your further individual
advancement academically.
Once you have completed your “station work” submit your packet and
ask me “what is next???”
Reflection: How well do you understand macromolecules? Explain your
answer.
CONCLUSION: Complete the following once you have
completed your station work.
