Low Density Lipoproteins Studies Have Shown
1,106 wordsThe French Paradox is something many people today are getting quite familiar to. Studies have suggested a close relationship between the moderate consumption of red wine and a healthy heart. This phenomenon goes under the name French Paradox because although the French eat as much saturated fat as Americans, they seem to enjoy better overall cardiovascular health. Even though these studies show that polyphenols, which is in red wine, can help your heart, blood circulation, and many other things,...

2 H 2 O Creatine Phosphate
1,714 wordsWith the aid of diagrams provide a summary of how the following energy systems work. Energy systems; introduction Energy systems are cellular levels processes used to produce Adenosine Triphosphate (ATP) figure 1. This is an adenosine molecule linked to three high-energy phosphates that acts as an energy store for the cell. The energy is released when ATPase, an enzyme, reacts with ATP to produce ADP and Pi, e. g. ATP ADP + Pi There are three energy systems that do this; The Creatine Phosphate S...

Gel Electrophoresis Carbon Dioxide
2,361 wordsPyruvate Decarboxylase There are two functions of the pyruvate decarboxylase. Pyruvate and hydroxythyl converge together while carbon dioxide molecules are eliminated. Than, hydroxy ethyl group transfers and attaches to TPP to the lipo amide from the E 2 component of the complex. The final transfer brings the molecule back to its original form. (Function) The molecular weight of the enzyme was found to be 240, 000 by polyacrylamide gel electrophoresis (Oba). There are 548 amino acids and very si...

Prince William Sound Advancement Of Science
1,394 wordsCleaning Up after the Exxon Valdez Was A Mistake Through many hours of research I have determined that the spill cleaning techniques used to clean the Prince William Sound area of Alaska did more harm than leaving the oil where it was. The Alaskan oil spill has become the most studied and managed event of its kind. Although there is not much that can be done about the marine life that came into direct contact with the crude oil, the geologic effects that the oil introduced into the area should h...

Carbon Monoxide Carbon Dioxide
4,029 wordsThe Exhaust Systems Exhaust Systems The exhaust system on a car is the most important device to keep our environment clean. Many exhaust emissions from the engine such as water, oxygen, nitrogen, and carbon dioxide, are of little concern. Others, such as hydrocarbons (HC), oxides of nitrogen (NO), and carbon monoxide (CO), can cause environmental and health problems if not controlled. Hydrocarbon emissions react with sunlight, which cause photochemical smog. The exhaust system controls these the...
