Enzyme Reaction Rates Under Different Conditions Introduction In this lab you will observe how the rate of a reaction is changed as certain factors are changed. You will observe how changing factors like temperature‚ pH‚ substrate concentration‚ and enzyme concentration changes the rate of an enzymatic reaction. In this experiment you will act as an enzyme by breaking toothpicks witch act as substrates. After observing the results of this experiment you will be able to determine what causes the

of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending on the type of reaction they control. Hydrolytic enzymes accelerate reactions in which a substance is broken down into simpler compounds through reaction with water molecules. Oxidising enzymes‚ known as oxidises‚ accelerate oxidation reactions; reducing enzymes speed up reduction reactions‚ in which oxygen is removed

If i increase the intensity of the rate of photosynthesis would drastically increase which is the light bubbles would be emitted in the jar in one minute because of the fact that the more photons of light that fall on a leaf then more chlorophyll molecules would be ionised and the more ATP and NADPH are generated If i increase the intensity of the rate of photosynthesis would drastically increase which is the light bubbles would be emitted in the jar in one minute because of the fact that the more

Total CO2 Evolved by Different Concentrations of Convollaria roots. Actual values are the graduated pipette readings. For CO2 evolved values‚ subtract the initial reading from the actual reading. This is the amount of CO2 accumulated over time. | Time (min) | Tube 1 | Tube 2 | Tube 3 | Tube 4 | | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | Initial reading (I) | 0.05 | | 0.01

developing country. A country such as Germany is a developed country because it has a negative rate of natural increase. The rate of natural increase is the crude birth rate minus the crude death rate of a population. The rate of natural increase for Uganda is 3%. The doubling time for Uganda is 23 years. The doubling time for Germany is that ere is no doubling time. This is because Germany’s rate of natural increase is -0.2%. Uganda’s GDP is $1‚390‚ GDP is the average salary for one person‚ in one year

One of the effect of imposing minimum wage to the economic is poverty rate increase. Most of the people will think that if a firm pay their low wage employees more‚ so the workers will earn more and will not live in poverty. That is an incorrect statement. When government raise the minimum wage‚ the firms will incur more expenses due to they have to pay more on the wages. Therefore‚ the firms will have 2 options. First‚ they hire less worker and use machine to replace the workers. With this option

Investigate the effect of concentration on the rate of a reaction Research question: To what extent does the concentration of hydrochloric acid affect the rate of the following reaction: 2 HCl(aq) + CaCO3(s) → CaCl2(aq) + H2O(l) + CO2(g) Data Collection and Processing: Table1: Different volumes of Co2 gas produced by Different concentrations of HCL acid. Volume of CO2gas formed from 5 different concentrations of HCL acid ±0.5ml 5 different concentrations of HCL acid (Mol) ±0.5ml Time (sec) ±0

and neutralise stomach acid. Planning Aim To determine how the surface area of the tablets affects the rate of the reaction. To determine which form of tablets gives the biggest surface area resulting in the fastest reaction rate. Investigation question: What is the relationship between the total surface area of the tablets and the rate of the reaction? Hypothesis: The rate of reaction will be the fastest when the tablets crushed into powder as there is a bigger total surface area resulting

Does concentration affect the speed of chemical reactions? Problem: We are proving that “concentration” (the amount of reactants) is one of the things that can affect the speed of chemical reactions. We are also finding a way to keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister
