The Effects of Substrate Concentration and Temperature on a Catalase Reaction Rate Introduction Catalase is a vital component in the human body. The most crucial of which would be Enzymes, these are protein catalysts. A catalyst speeds up a chemical reaction rate. Virtually all chemical reactions within the human body require a catalase enzyme to be completed in the proper amount of time. The decomposition of hydrogen peroxide to oxygen and water can be completed with the catalase enzyme…

affect the rate of reaction? Problem: What effects does temperature have on the rate of reaction? Purpose: The aim of this investigation is to investigate how changing the temperature of sodium thiosulphate affects the rate of reaction in a chemical reaction. In order to complete this practical the temperature will be changed three times and the rate of reaction will be measured each time. Variables: Independent: -the temperature of the sodium thiosulphate. Dependent: -the rate of…

The rate at which a reaction takes place can be affected by the temperature, the concentration, the particle size, and by using a catalyst but two that really affect the reaction are temperature and concentration of the solute and solvent. The rate of a reaction is determined by the temperature and the concentration which in this case determine how fast or slow the reaction will occur. In both cases something is being increased, for example, placing solutions A and B in the warmed water…

The effect of music genre on heart rate and blood pressure By: Kristin Hall Introduction: Heart rate measures the speed of the number of times the heart pulses per a unit of time, normally beats per minute (Biology Online, 2011). The number of pulses is based off the number of contractions of the ventricles. This number shows how much blood is flowing through the body, and thus how much hemoglobin and oxygen is being transported. When muscles become active they require more oxygen to function…

Kinetic can be defined as a study of the speeds or the rates of chemical reactions. The factors that could affect the rates of the reactions are physical state, reaction temperature, catalysts, pressure, concentration of solution, and reaction time. The change of the speed of the reaction can be predicted based on the different reaction conditions. Kinetic study is important because it can describe information about the reaction mechanism. The concentration has affected the frequency which the…

Aims & Their Importance Our aim is to find out if there is Interest Rate Parity (IRP) between the USA and China, over an annualised period of 10 years (April 2005-April 2015). We think that this is an important topic as the US are the current global economic superpower, and China is an up and coming power. Also, as there is a lot of trade between the two countries, and we know that china is highly dependant on their exports for GDP growth. A higher Yuan causes exports to slow ( 1% decline for…

1.5.1.2 TERM STRUCTURE OF INTEREST RATE Mishkin (2009) states that the term structure of interest rate explains that bonds with the same risk and liquidity have different interest rates because the bonds time to maturity are different from each other. He also states that the yield curve illustrates how the returns of bonds and maturity changes over time. There are four approaches that elaborates on the different shapes of the yield curve, they are the expectation, liquidity-premium, segment…

interest rates, foreign exchange markets and rates The questions that I will answer for this week’s assignment are as follows: Why the simultaneous targeting of the money supply and interest rates is sometimes impossible to achieve? How do central banks intervene in foreign exchange markets? What did the Bretton Woods Agreement do to the ability of foreign exchange rates to fluctuate freely? Targeting Money Supply and Interest rates Firstly, the Fed targets money supply and interest rates in…

heavier and drastically. The heavy catch is that discount rates almost usually change significantly over a period of time, and the IRR method is solely based upon one internal rate of return. Not only that, the basic IRR calculation is completely ineffective when it is evaluating a project with a mixture of multiple positive and negative cash flows. In this case, a single internal rate of return [IRR] cannot possibly be used. IRR is the discount rate that makes a project break even, in the first…

affect enzyme function by increasing the reaction rate because as temperature increase so is the rate of reaction and extremely high or low pH will result in the denatured by decreasing the reaction rate. The function of this experiment was to investigate the influence of the concentration of enzyme on the rate of reaction. The rate of reaction in this experiment was subjected by the amount of Guaiacol, H2O2, Extracts, and Buffer (pH5). The reaction rates with different enzyme concentration at…
