  • G Proteins And Change Into Enzymes
    364 words
    G proteins, named after the fact they bond with guanine nucleotides, are largely responsible for intercellular communications within the human organism. These transmissions regulate such functions as hormone secretion, muscle cont action, and even cognition. These transmissions take place because of chemical reactions between enzymes that bind with the G proteins and change into enzymes that trigger other chemical reactions. These chemical reactions induce cellular changes to occur by increasing...
  • Chemical Reactions Molecule By Molecule
    2,121 words
    Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named Georg Ernst Stahl was the first to postulate on chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the air from all substances during combustion. He ...
  • 100 Of The Copper Metal
    713 words
    Intro In Lab #5 five we will be exploring the cycle of copper through many chemical reactions. What we are going to do is take a piece of copper metal put it through a series of reactions that change it's state of matter and chemical formula, but in the end, we will return it to it's normal solid state. The idea of this lab is to try to recover as close to 100% of the copper we started with. Theoretically, this is possible, but for inexperienced college students, retrieving 100% of the copper me...

  • Science Behind The Inflation Of An Airbag
    906 words
    Automobiles are being equipped with airbags that inflate on collision to protect the driver or passenger from injury. A car's airbag is located on the steering wheel, this airbag is for the driver, and on the dashboard, this airbag is for the passenger. Automobile airbags are inflated by the electrical system and sensors in the car that triggers a chemical reaction to occur. When a car is involved in a car accident the airbag rapidly inflates and deflates to cushion the driver or passenger. In a...
  • Apple Discolors After A Reaction With Oxygen
    512 words
    Movies. Funny, entertaining, dramatic creative and a whole lot more. Aks a child if they have seen Harry Potter, an obvious answer 'YES'. SO what do movies contain to lure as into them. This as sey will observe the techniques used to attract the audience. Firslty movies relate to our lives (well almost all of them) they show us what we want to see. g jk. gtk The results shows that the browning process of the apples is slowed down / stopped once the apple is in an oxygen free environment. By burn...
  • Chemistry And Biology
    537 words
    Why is knowledge of chemistry important to biology? Maier, Scott Advanced biology 10/7/99 Biology is the study of all living things and chemistry is the study of chemicals and their interactions. So, how are they related? Our bodies are made up of hundreds and hundreds of chemicals. We just don? t think of them like that. Did you ever wonder how your body turns food into energy? It's a chemical reaction. That's chemistry involved in biology. Our bodies have hundreds more chemical reactions. A ch...
