Would YOU Eat This?
On the left side of your journal, describe
your thoughts of the video. Answer the
questions:
What is food?
And why is it important?

Synthesizing & Digesting:
Two basic reactions:
1) Dehydration
synthesis
– Dehydration – water
lost
– Synthesis - build
• = removing a water
molecule to build a
polymer!!
Synthesizing & Digesting:
2) Hydrolysis
– Hydro – water
– Lysis – break apart
• = Using water to break apart polymers!
• DIGESTION!!!!!!!!
With a partner, define a monomer
and a polymer…
What is another everyday
example you can think of that
have monomers and polymers?
cell wall
Cellulose

With a partner, discuss the
following question:
What are two ways that carbs and
lipids are alike?
RNA
Peptide Bonds
IMPORTANT:
• The order of the amino
acids determines the
shape of protein
• Shape determines
FUNCTION!

 Primary
Structure is
just the specific order
of amino acids in the
chain.
 Secondary Structures
are either a helix or a
pleated sheet formed
form hydrogen bonds
reacting between the
amino acids.
 Tertiary
Structure
occurs because of
attractions between
the alpha helices and
pleated sheets.
 Quaternary
Structure
is a protein consisting
of more than one
amino acid chain.
With a partner, discuss the
following question:
How are carbohydrates and
nucleic acids related?
Enzymes
Proteins
Carbohydrates
Lipids
Nucleic Acids
With a partner, discuss the
following question:
How do we obtain carbon from the
carbon cycle?
