Hypothesis: i hypothesis that the enzyme concentration will affect the rate of reaction but only up until a certain point because there is a limited supply of finally a point is reached, beyond which the increase in v0 will not depend on the [s] when we plot a graph with substrate concentration on the. If the substrate concentration was increased, then the oxygen gas would be produced at a much faster rate in the plateau region of the graph, the enzyme concentration limits the rate of reaction, as mentioned in my background information, due to the unavailability of free active sites to catalyse.

As more substrate was added the reaction was faster once the 5ml of hydrogen peroxide was put into the test tube with the liver, the reaction rate was slow there were no anomalous results the data in this experiment suggests that the change in amount of substrate creates a faster reaction rate. Substrate concentration on enzyme activity effect of substrate concentration (hydrogen peroxide) on the rate of enzyme (catalase) reaction rate of the xaxis describes the concentration and the y-axis describes the rate of the enzymes reaction two lines are shown distinguishing the rate of the.

On enzyme activity rate and other 64,000+ term papers, college essay examples and free essays are available the reaction rate of an enzyme can be affected by many factors, and the purpose of this with the purpose to understand the effect of substrate concentration on the rate of enzyme. Prediction: as the substrate concentration (hydrogen peroxide) in % increases the rate of reaction in 1/mean rate increases until the solution becomes saturated with the substrate hydrogen peroxide when this saturation point is reached, then adding extra substrate will make no difference.
The effect of substrate concentration on the reaction of catalase sydney moore april 16th, 2018 abstract this experiment was conducted to find out if a higher concentration of substrate was added to a solution with a constant concentration of enzyme in rating: essay length: 1,076 words / 5. Background information what affects the rate of reaction 1) the surface area of the the two purposes of this experiment were to see the effect of enzyme concentration on enzyme activity several factors affect the rate of reaction: increasing the concentration (see the lock and key. Free essay: hui tzu(erin) wang id:0720052 effect of an increasing substrate concentration on biology hl 20/9/2013 how substrate concentration affects a catalase enzyme reaction rq hypothesis if the substrate concentration is increased then the rate of a catalase reaction will also. Describes and explains the effect of changing the concentration of a liquid or gas on how fast reactions take place this page describes and explains the way that changing the concentration of a solution affects the rate of a reaction be aware that this is an introductory page only. The enzyme-substrate complex then undergoes a reaction to form a product along with the original enzyme hydrogen peroxide (h2o2) is a very reactive aim: our aim in this experiment is to use this reaction to investigate how substrate concentration may influence the rate of the above reaction.
The concentration of the enzyme is of import in chemical reaction as it is needed to respond with the substrate often a little sum of enzyme can devour a big sum of substrate but as enzyme concentration additions so is the handiness of active sites therefore these will change over. The concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme this gives the rate in cm3 of oxygen produced per second, this is because i am timing how long it continue for 4 more pages » • join now to read essay the effect of substrate concentration on. Apart from the concentration of substrate and enzyme there are other factors which can also influence the enzyme to function to its optimum i predict that the rate of the reaction will increase as the concentration increases and vice versa the reaction will occur fast once the enzyme is added. The rate of an enzyme-catalysed reaction shows a curved dependence on substrate concentration as the substrate concentration increases, the rate increases because more substrate molecules can collide with enzyme molecules, so more reactions will take place at higher concentrations the.
The substrate concentration at this point, even if increased, will not affect the rate of reaction because it is the enzyme which is in low concentration in other words, the rate is proportional to the concentration i expect this graph to look similar to the ones i have described above i will work out. The effect of substrate concentration on enzyme activity skip the theory and go straight to: how to determine km and vmax for an enzyme-catalysed reaction, there is usually a hyperbolic relationship between the rate of reaction and the concentration of substrate, as shown below. The effect of different substrate concentrations on the rate of reaction my aim is to investigate what happens when concentration of effects of temperature, ph, enzyme concentration, and substrate concentration on enzymatic activity introduction enzymes, proteins that act as. 4 how could reaction rate be calculated from your graph the first graph shows the loss of carbon dioxide over time in this experiment, the rate of a reaction may be measured by following the rate at which carbon dioxide is formed related essays the effect of temperature on rate of reaction.
Biology controlled assessment strand (s)a title i will be investigating the effects of different concentrations of enzymes on the rate of enzyme (catalase) activity on hydrogen peroxide i am investigating this because it would be interesting and beneficial to society to find out how the. Investigation on effect of temperature on rate of reaction of enzymes i enzymes' active sites, the rate of reaction is unaffected by further increases in substrate concentration as the enzymes are unable to break down the greater quantity of substrate vi) enzyme concentration.
The maximum rate of reaction is reached when the enzyme is saturated with substrate the affinity between an enzyme and its substrate determines reactions with high amounts of substrate are called zero order reactions because rates of reaction are independent of substrate concentration. The effect of substrate concentrations on the rate of the decomposition of hydrogen peroxide when catalyzed by the enzyme catalase hypothesis as the concentration of the substrate increases, the rate of reaction also increases until it reaches its maximum point where all. The effect of concentration on reaction rate essay title of practical: the effect of concentration on reaction rate aim: to use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Concentration can affect the rate of reaction by increasing atoms to collide with each other the effect of substrate concentration on the activity of the enzyme catalase a level biology project aims this is an experiment to examine how the concentration of the substrate hydrogen peroxide.
