Porsche
Porsche I have narrowed down my project to just Porsche vehicles. I am not going to talk about the man behind the car to much. I have found several web sites that have criteria about Porsche and their different models and their performance. I will discuss these subjects along with others. The history of Porsche will be discussed. I will also talk about some different models such as the 911 GT3. I will also discuss the GT1 and GT3 race seriesI will also discuss Porches latest press releases. His
The Slide Rule
The Slide Rule
The Slide Rule The slide rule is mechanical device used by mostly engineers and scientists for fast and accurate multiplication, division, to find roots and powers, and other simple math problems. It consists of a fixed section with upper and lower parts marked with different logarithmic scales, a center part that slides between the parts of the fixed section and is also marked with scales, and a clear cursor that can be moved to help align the scale marks. The slide rule has almost been totally

Investigating the Effect of Lipase Concentration on the Breakdown of Fat in Milk INTRODUCTION: Enzymes are proteins which can catalyse chemical reactions without changing themselves. The enzyme lipase breaks down the fat in dairy products such as full-cream milk for people who are lactose intolerant. Lipase acts on its specific substrate, lipids produces fatty acids. If enzyme concentration increases, random collisions between the substrates and active sites of enzyme increase due to the increas

Investigating effect of temperature on the activity of lipase
Investigating effect of temperature on the activity of lipase This practical gives you a chance to: investigate how lipase activity changes with temperature consider how indicators can help us to follow chemical reactions. Procedure SAFETY: Keep the phenolphthalein solution away from naked flames. Wear eye protection and quickly rinse any splashes of enzyme solution or sodium carbonate from the skin. Make sure you know what to do if a thermometer is broken. Investigation a Label a test tube

Investigating an enzyme controlled reaction: catalase and hydrogen peroxide concentration Objectives to investigate the effect of substrate concentration on the activity of catalase to evaluate a practical protocol Procedure SAFETY: Wear eye protection and protect clothing from hydrogen peroxide. Rinse splashes of peroxide and pureed potato off the skin as quickly as possible... Investigation a Use the large syringe to measure 20 cm3 pureed potato into the conical flask. b Put the bung secur

Units,Dimentions, Measures and calabration. CHEMTUTOR Measurement is the most useful form of description in science. Often the most useful measurements are those that have a number and a unit, such as 12.7 inches.' Here '12.7' is the number and 'inches' is the unit. This unit of inches in the example is one of the common units in the dimension of length. A number, then, is an expression in numerals. A unit is a recognized way to divide the essence of a dimension for measurement, and a dimension

Stage 2: Human BiologySummative Practical: Pepsin Background Information: What are enzymes and how they work?Enzymes are necessary proteins that are crucial in the maintenance and activity of life. CITATION Amaed l 1033 (Inc, Undated). Enzymes increase the rate of a chemical reaction without itself undergoing any permanent chemical change. All chemical reactions that occur within a living organism rely on the catalytic actions of enzymes, which is why enzymes are called Biotransformation. Curre

Lipase
Background information: Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur. The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/substrate complex. Enzymes are very specific and don\'t just grab on to any molecule. The active site is a specially shaped area of the enzyme that fits around the substrate. The activity of enzymes is affected by three factors; temperature, concentration, and
