Yet Another Scribepost by Josh B, on Enzymes, p4sts2010

This is the Scribepost for the day of October, the 7th, of the year 2010, The Year of the Tiger, also the 29th of Tishrei, 5771

I apologize in advance for anything I may miss, for I found out that I was to be the scriber in the middle of class and hadn't taken notes.

Don't misunderestimate my note taking power, by the way. (Word from George Bush).

Homework

-The only thing was to finish the pre-lab for tomorrow, if you didn't during class.

What we did today

-The very first thing that we did today was turn in both labs. Yes, both. The recent diffusion one, and the not-so-recent microscope lab, with the frog blood. These labs will be counted as grades, as surprising as it may seem. So turning them in if you haven't yet is probably a good idea.

We also went over some of the later questions from the diffusion lab, but seeing as I am a GOOD STUDENT and turned in both of my labs, I can't give you the answers.

-Next, Mr. Paek decided to be insane and put Potassium Iodide (KI) into a large cylinder that had some Hydrogen Peroxide (H2O2) in it. It exploded... in a huge column of condensed steam that looked like a solid. It just kept foaming up and breaking off over the top of the cylinder. This picture isn't from class, but sort of portrays the reaction.

This was really cool, and if you missed it, then that sucks.



-Mr. Paek also decided to use a new system of punishment for talkative people. If you are talking too much, he will take you to the front of the room and make you put your finger in Hydrochloric Acid for several minutes. Just kidding (or am I...). Actually, if you are talking, your name will be written on the board, and a point will be taken off your grade. Another offence, and that number is doubled. For more information, talk to Jake C.

-ATTENTION PEOPLE- WE HAVE A SUB TOMORROW! If any one of us were to be rude and talk, everyone looses points. You really don't want to be the person responsible for that. So be nice and do the lab and all will be well.

-WOAH! Another lab! Again! This lab can be found on pages 24-32 in the UP. It is rather long, but I am sure that most of us can handle it. It is all about the effect of temperature on enzyme activity. Basically, we just need to follow the instructions, because I don't feel like going through the entire lab. We will need to fill three test tubes with a small combination of stuff, and record our data in the table. The bubble column height is measured when the bubbles stop rising. The higher the bubble column, the more enzyme activity there is. In part B, we will need to get the enzyme catalase to a certain tempertaure, then answer some questions, do some tables, and make some graphs. (CAUTION: I downsized this lab quite a bit).

-Now for the boring part: the notes from today.

Enzymes

Are protiens

The subtrait is the material that the enzyme works on

H2O2 to H2O+O2

Where H2O2 is the substrate and "to" is the enzyme

Catalyst-an enzyme that speeds up the rate of a chemical reaction

Enzymes are affected by pH(the acidity of something) and temperature

Catalase-an enzyme found in the blood cells. It spefically speeds up the breakdown of hydrogen peroxide.

Thats all, folks, except for some pictures

I like money

THE VICTIM FOR TOMORROW WILL BE CHOSEN BY THE FORCE OF GOD!

GOD CHOOSES... Richard
