Glucose
Ribose
Dextrose
Fructose
Proteins do everything!
Monomer:
Amino Acids
Structure:
Many amino acids
hooked together = a
polypeptide
Function: make any part Test to Identify:
of an organism; muscle
contraction
Biurets Test
Last source of energy
Which organic molecule?
• Insulin – important hormone,
composed of 51 amino acids
• Made in the pancreas; released
when stimulated
• Causes cells in liver, muscle, & fat
to take up glucose from blood; store
it as glycogen in the liver and
muscle
Which organic molecule?
• Hemoglobin:
Carries oxygen in red blood cells
Lipids = Fats, oils, waxes
and steroids
Monomer:
Fatty Acids
Function:
Energy storage;
insulation; and making
cell parts
Structure:
Many fatty acids hooked
together in a chain
Test to Identify:
Brown Paper Test
Lipids are . . .
• Insoluble in water
– (nonpolar molecules - not attracted
by water molecules)
• energy storage (long term)
• insulation
• protective coverings
• major components of membranes that
surround all living cells
Triglyceride
3 FATTY ACIDS AND A GLYCEROL
Nucleic Acids = genetic
information
Monomer:
Nucleotides
Function: DNA and RNA
- our genetic code
- instructions for making
proteins
Structure:
Many nucleotides
hooked together in
long chains
No Test

2. They speed up chemical reactions
Enzymes are Specific
A specific enzyme will fit it’s specific
substrate
Lock and key fit
Enzymes are used over and over
Enzyme Substrate Activity
Instructions
1. Get the following:
a.
b.
c.
d.
1 Piece of construction paper
1 blue hand out
1 pink handout
Scissors and glue
2. Cut out substrates first!
3. Then cut out the enzymes and make the
substrate enzyme complex.
4. Then cut the products, and glue them beside
the complex.
5. After you have cut out and pasted all
complexes answer the 5 questions on the back
of your notes from today on Enzymes
