Honors Assignment on Enzymes due 9-10-12

This assignment is due on Monday- it will not be accepted late- NO EXCUSES.

Don't put it off to the last minute- you need to make sure your home computer can run the simulation or use the school computers after school!

Go to:   http://www.sascurriculumpathways.com/portal/

sign in as a student,  here is your login:   spoint

once logged in you can put the number 1 in the quick launch box. It has a green go button next to it and QL# in the box. just put the 1 in the box, click the go tab and it will take you to the assignment.  

It's called :VLab: Enzymes 

Investigate how changes in pH, temperature, substrate concentration, and regulators affect an enzyme and its activity

You will need to print off the data and observation sheets as well as the analysis and conclusion sheets.

You must answer all questions and complete all data tables and graphs.

It may look like a lot at first, but if you go step by step you'll see that you are mostly just writing down exactly what you see in the simulation and the tutorial. It is not difficult,  everything goes in order.

I will stay after school Tuesday and Thursday in the computer lab if you would like to stay and use the school computers to complete the assignment.

NEW WEB PAGE WITH DOCUMENTS

Hey, I created a new site where I can upload documents and share a calendar. If you are wondering about what's coming up or you need a handout because you were absent go to this site.
I will soon be transferring everything to this one site!

Organic Compound terms

window panes for Organic compounds:

1. Carbohydrate- organic compound made up of carbon, hydrogen and oxygen atoms whose primary job is to provide a quick source of energy to the organisms that consume it.

2. Lipid- organic compound made up of carbon, hydrogen, and oxygen. It has two main purposes in organisms: provide storage for energy and build membranes ( thin covering around all of your cells).

3. Protein- organic compound made up of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur atoms. The main jobs of proteins are: to build tissue in the body, to make up hormones and to build enzymes.

4. Nucleic acids- organic compounds made up of carbon, hydrogen, oxygen, nitrogen and phosphorous. The main job of these compounds is to carry our genetic code which determines everything that is made in our bodies. Examples are DNA ( deoxyribonucleic acid) and RNA ( ribonucleic acid)

5.Hormone- a chemical signal (made out of proteins) that travels through our bloodstream and lets other parts of our body know how to grow or what to make. (ex. progesterone- a hormone that is active in pregnant women and helps to prepare the mom's body to hold and care for a baby).

6. Enzyme- a type of protein that is responsible for helping to speed up chemical reactions in our body. In chemistry, or in reactions outside of our body, this is called a catalyst.

7. monosaccharide- a simple sugar (carbohydrate), this is a sugar composed of only one molecule- glucose is a monsaccharide. (mono=one)

8. polysaccharide- a type of sugar made up of a long chain of single sugars. (poly = many)

9. cellulose- a type of sugar found only in plants, it helps to build outer coverings of vegetation ( the yellow shell of each little piece of corn is made of this). we can not digest cellulose.

10. Starch- a complex carbohydrate made up a really long chain of glucose molecules. This is the form that plants store their sugar in.

11.Insulin- a hormone made in the pancreas that helps break down sugar in the body.

12.Hemoglobin- a protein that makes up your blood, it carries iron and oxygen ( you can normally carry 4 molecules of oxygen on each cell).

13. Glycogen- the stored form of glucose, it is stored in our liver.

14.monomer- a molecule that exists by itself - only one molecule of something = glucose

15. polymer- a molecule that exists as a long chain of monomers connected by bonds= starch

16. Organic compounds- compounds that have the element carbon as the central/ essential connection.

17. atom- smallest unit of an element.

18. nucleotide- smallest functional unit (or piece) of a nucleic acid. It consists of a sugar, a phosphate and a nitrogen base.

19. double helix- the shape of a DNA molecule, it resembles a twisted ladder.

20. single helix- the shape of a RNA molecule, it resembles half of a twisted ladder.

Lab safety

 
 Here's a short video to review lab safety issues.
This is a Biology class so we probably won't be working a whole lot with toxic chemicals or gas flames but you should always enter a lab situation knowing and using best practices for all possible situations, enjoy:
http://www.wired.com/wiredscience/2009/10/puppet-lab-safety-video/

Our first week will be focused on the smaller pieces of Biology.
We'll be learning about biochemistry so you'll need a refresher on atoms, molecules and pH in order to  really understand what makes organic compounds and how they work.

Here's another clip by the same people that did the safety song, only this one is about really small things; Nano sized things!

Now check out this interactive on size and scale of cells and other things

what's bigger an e.coli bacterium, a paramecium or a ribosome?
