Effect of different temperatures on the rate of an enzyme controlled reaction I will place starch and amylase into five water baths which are at different temperatures‚ and record the time it takes to break down the starch in the solution. Independent variables The independent variable is what I am going to change in my experiment. In this case it is the temperature of the water in the five water baths- 10‚ 25‚ 40‚ 55‚ 70 degrees Celsius Dependant variable This is what will stay the

20 THINGS YOU CAN DO TO CONSERVE ENERGY Whenever you save energy‚ you not only save money‚ you also reduce the demand for such fossil fuels as coal‚ oil‚ and natural gas. Less burning of fossil fuels also means lower emissions of carbon dioxide (CO2)‚ the primary contributor to global warming‚ and other pollutants. You do not have to do without to achieve these savings. There is now an energy efficient alternative for almost every kind of appliance or light fixture. That means that consumers

2. Justify your allocation based on your outlook for systematic risk in the U.S. Systematic risk is primarily based on the risks that are associated with actual or real events that may affect the market. This includes interest rates‚ inflation‚ wars and all that can affect the market and cannot be avoided through diversification. Systematic risk can be associated with riskier securities if and when compared to bonds. This rate of return is mainly unpredictable but can be profitable. My reasoning

Title: “The Effect of Substrate Concentration‚ Enzyme Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.

______________________ Evaluation of the Gas Law Constant Objectives In this experiment‚ we will determine the Ideal Gas Constant‚ R‚ which relates the number of moles of gas present to its volume‚ pressure and absolute temperature. Background To see how "R" was derived‚ we must look at the proportionalities defined by the other fundamental gas laws. For example‚ Charles’ Law showed us that the volume of a gas sample is proportional to its absolute temperature at constant pressure. Thus V ∝ T abs

Wine-making is essentially a chemical process. It involves a chemical reaction in which sugars are turned to alcohol and carbon dioxide in the presence of yeast. There are also many other chemical processes going on which affect the strength‚ appearance‚ colour and taste of the wine. Grape Ingredients Wine is made from grapes. In addition to water‚ grapes contain two different sugars: glucose and fructose‚ tartaric acid‚ malic acid‚ amino acids and a few other chemicals. The chemical processes of

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates
