Rough Draft of your Research plan is due on notebook
paper or typed by 10/24 (page 7)
If you are growing plants for Science Fair you need to start
Start working on your Science Fair Laboratory Composition
Notebook. Follow the instructions in your Science Fair
packet carefully. It tells you exactly what to do and how
to do it. (Page 8)

Cell Exam is on 10-16-14 (you should have read chapter 7)
District Nine Week Exam is on Tuesday, 10-21-14:
Review your interactive science notebook a few minutes each day.
Print out the old study guides with answers from the class website.
Review the power points posted to our class website
Quiz yourself or have someone quiz you
Make flash cards
Come up with memory devices such as: hypOtonic solutions cause
cells to swell.
And of course…study the review you picked up at the door yesterday.
Band students who are out 5th-7th……come during your band class on
Wednesday to make up the exam.
Quick Notes
Enzymes are proteins that speed up
chemical reactions. They are called catalysts.
They are very important in cellular metabolism.
For example: Cells natural produce hydrogen
peroxide….a poison. Enzyme in your cells quickly
convert the hydrogen peroxide into water
and oxygen.
Enzymes are not used up in a chemical reaction. They
are recycled. The substance they bind to is called
the substrate (example above would be hydrogen
peroxide)
Enzymes lower the activation energy required to
get a reaction going.
Proteins are made up of amino acids (amino acids
are the monomers that make up proteins). Proteins
can be found in the cell membrane. Some proteins
are enzymes (catalysts).
Lipids are fats. They are a major part of cell
membranes.
We get proteins, lipids and carbohydrates in our diets.
Lipids contain the most energy.
DNA is found in the nucleus of Eukaryotes
and is the genetic material that codes for the
proteins.
DNA contains carbon, hydrogen, oxygen, nitrogen
and phosphorous atoms.
