Catalase investigation essay

Investigation - Hydrogen Peroxide Biology Investigation - Hydrogen Peroxide An investigation into how the concentration of the substrate 'hydrogen peroxide' affects the rate at which it is broken down to oxygen and water by the enzyme catalase Hydrogen peroxide is released due to many metabolic reactions in the body, which gives toxicity to the living cells.

According to the Michaelis-Menton mechanism, there are three principal features of many enzyme catalysed reactions and they are as follows: All reactions involve two reactants which need collisions between them for particles to proceed.

Temperature — Reactions go faster as temperature rises. Get cm3 beaker and fill with water to about the cm3 mark with water at a specific temperature. Many enzymes work best in neutral conditions but some prefer acids and some prefer alkalis.

Is my conclusion valid. Subsequently, the evidence for or against my prediction regarding the enzyme activity in relation to temperature will be more strong, and, more reliable.

Induced Fit Theory The induced fit theory states that the binding of a substrate to an enzyme causes a change in the shape of the enzyme.

As well as this, hydrogen peroxide can be very harmful if it enters the eyes. The Primary structure of Catalase is the sequence of amino acids that make up the protein [Catalase has amino acids, as well as one haem group].

The enzyme forms the active site from small numbers of amino acids. The reason for finding the SD is to be able to see how much the results tend to diverge from the average, and therefore be able to see how accurate and consistent your results are. If they do, that is also another hazard, and should be cleared up and disposed of in an appropriate fashion.

Role of hydrogen peroxide in the cytotoxicity.

Investigating an enzyme-controlled reaction: catalase and hydrogen peroxide concentration

While the water is reaching the desired temperature, get potato and bore out a cylinder with cork borer. The variable to be tested was the substrate concentration of the reaction, in this case the hydrogen peroxide. Record the quantity of oxygen evolved in each reaction. This is a variable which will be harder to control.

Individual students may then have time to gather repeat data. Investigation into the Enzyme Activity of Catalyze in the Decomposition of Hydrogen Peroxide Essay Sample. In this pre-designed procedure the enzyme activity of catalase in a potato was tested, in the form of measuring the volume of the Oxygen (O2) released by a catalase – hydrogen peroxide (H2O2) reaction in the span of one minute.

Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples.

Essay The effect of catalase concentration on the breakdown rate of h2o2 - The effect of catalase concentration on the breakdown rate of h2o2 The effect of catalase concentrations on the rate of Break down of hydrogen peroxide Scientific knowledge and understanding: A rate is a measure of change that occurs in a given time whilst a reaction is the interaction of substances undergoing chemical.

Therefore, catalase would be most active at around 37 degrees body temperature.

This means that in this experiment catalase would be most active in the water bath that is at 40 degrees Celsius. We will write a custom essay sample on Investigation of temperature on catalase activity specifically for you.
