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)

District Nine Week Exam is on Tuesday, 10-21-14. Review your interactive science notebook and print out the old study guides with answers from the class website.

Cell Root Word Quiz is TOMORROW 10-14-14

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.

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.

 

 

Quick Notes

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.
