Bellwork: October 1
Please write the question and your
answer.
1. What do disaccharides, such as sucrose, and
polysaccharides, such as starch, have in
common? (Think about the parts of each of
the bolded words!)
Science Fact of the Day
• Salt water is 4 times saltier than our blood. By drinking
it, your kidneys would need to use up a large amount
of water just to get rid of all that excess salt. This
means that you would actually die of thirst from
drinking seawater.
CO: I will understand the characteristics
of proteins and compare proteins to the
other biomolecules.
LO: I will write notes. I will plan a lab
with my lab group.
Functions:
Structure:
•Peptide bonds connect the amino acids
•Enough amino acids connected together will
cause the protein to fold and create a new
shape
Elements:
Good to know:
•Carbon (C), Hydrogen (H),
Oxygen (O), Nitrogen (N)
Protein
Monomer:
Polymer:
How are proteins similar to lipids and
carbohydrates?
How are proteins different from lipids
and carbohydrates?
Structure:
Functions:
Controlling the rate of reactions (enzymes).
•Peptide bonds connect the amino acids
Regulating cell processes (enzymes).
•Enough amino acids connected together will Forming bones and muscles.
cause the protein to fold and create a new
Transporting substances into or out of cells.
shape
Helping to fight disease (antibodies).
Function is determined by shape!

How are the polymers of proteins
similar to the polymers of
carbohydrates and lipids?

Design Your own Experiment
1. Record the data given by your teacher for the
Alka-Seltzer reaction
2. Identify a variable that you can change
3. Write a lab proposal for the variable
4. Get teacher approval before you leave
5. We’ll run your experiments tomorrow! 
