PKU

(Pku)This stands for Phenylketonuria. This is a disease  that creates some kind of genetic disorder characterized by a deficiency in the hepatic enzymes. The enzyme is necessary to metabolize the amino acid phenylalanine. Usually they do screening for this in new born babies. The reason this is so bad is because it can create brain damage and if not taken care of or treated properly its progressiveness will create mental retardation. Later studies said that a healthy diet can help but in recent studies show that  in worse cases you need protein supplements and need to lower phe levels to safe range.

Graphs for lab



In this lab we used 3ml of water and 3ml of peroxide and different numbers of drops of yeast. What we did then was we mixed three different amount of drops in 3 different tubes with the same amount of water and peroxide. We then put a stopper with a pressure sensor on it. and watched the graph rise  we did 3 sets f three the first one had a variable  of different amounts of drops , the second we used different ph levels, and the last on we  had different temperatures. All of these showed different rates of reaction and we Graphed them.The graphs above the the different reaction rates and the amount of prssure put out by these reactions.

rattle snake venom

Rattle snake venom is a very toxic and some times fatal poison if not treated right away. There are three basic types of venom Hemotoxic, Cytotoxic, and neurotoxic. the first effects cardiovascular system the second effects the muscles and the last effects the brain and nervous system. The venom is a mixture of proteins and enzymes. When bitten by a snake with hemotoxic venom it typically acts to lower blood pressure and encourage blood clotting. When bitten by a snake with Cytotoxic venom it is designed to cause tissue damage and spread through out the body. And when bitten by a snake with  a neurotoxic venom it is designed to shut down the nervous system and the brain most the time causing paralysis or lack of muscle movement.
