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.

Protein

Structure: Functions:

Monomer: Polymer:

Elements:•Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N)

Good to know:

•Peptide bonds connect the amino acids•Enough amino acids connected together will cause the protein to fold and create a new shape

How are proteins similar to lipids and carbohydrates?

How are proteins different from lipids and carbohydrates?

Protein

Structure: Functions:

Monomer: Polymer:

Elements:•Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N)

Good to know:•The instructions to make proteins is stored in DNA

Controlling the rate of reactions (enzymes).Regulating cell processes (enzymes).Forming bones and muscles.Transporting substances into or out of cells.Helping to fight disease (antibodies).Function is determined by shape!

•Peptide bonds connect the amino acids•Enough amino acids connected together will cause the protein to fold and create a new shape

How are the functions proteins different from lipids and carbohydrates?

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

Reminders:

• Homework: Video Notes– “The Role of Enzymes” by VEA Australia -

New Zealand –Come in and use my laptop if needed.

• Buff Binder Check tomorrow! – Last grade of the six weeks!

For the remainder of class…Design Your own Experiment

1. Record the data given by your teacher for the Alka-Seltzer reaction

2. Identify a variable that you can change3. Write a lab proposal for the variable4. Get teacher approval before you leave5. We’ll run your experiments tomorrow!
