Catalase Gcse Coursework

Having done the experiment and looked at the results obtained, it was noticed that after 5 minutes there was still some unfiltered juice left in the funnel. In general, the human dependent methods turned out to be the least feasible, i. Place one respectively labelled syringe in each of the test tubes placed in the rack 10.

This method of measurement in products is extremely easy to measure and set up. Investigation of the effect of adding different concentrations of nacl to an enzyme-substrate (amylase-starch). It is possible to go on and look at the effect of temperature on pectinase and also substrate concentration, however the latter would be fairly difficult to measure.

The tertiary structure of the protein gives a certain shape to the enzyme and active site and therefore means that only certain shape substrate molecules will fit. This would have provided more data and therefore the graphs and rate of reaction would be more accurate. I therefore reject this method of measurement.

It is also time consuming, which isnt practical. The simplicity of this method does extent the time availability, which allows more results to be carried out. This is why my chosen method for measuring the rate of reaction is the gas syringe method.

Using the syringe provided with the starch, add a drop of starch in the first spot of both spotting tiles. Introduction enzymes are proteins that speed up and control certain reactions. I will look carefully at the rate of respiration of each substrate during certain times, so after 5 mins, 10 mins etc.

This method produces rather reliable and scientific results, if, of course, it is set up properly to measure. However, unlike timing and observation, this method is far more accurate, so a result or two less would not be much trouble. It is then carefully chopped up into small pieces using a knife and a tile. This means that there will be more frequent collisions in a shorter space of time. I also reject it because the carbon dioxide produced from the reactants can dissolve in the water which provides unreliability.

    An investigation to look at the effect of pectinase on other fruits such as plums or grapes or investigate changes in concentration of other enzymes such amylase or catalase. This could not be submitted as it is incomplete. The measurement of the experiment would be difficult. This is why i reject these two methods. Other uses include softening vegetables and extracting agar jelly from seaweed.

    The setting up of this method does not require so much hassle or attention, yet the procedure of measurement provides accurate results. In this method, there is quite a lot of equipment used, which makes the scientist depend on the equipment, and it not failing or breaking. Also, the fact that we have to reset it to 0 at the start, whilst the reactants are already reacting, provides unreliable timing, and therefore unreliable results. Investigate the rate of reaction between hydrochloric acid and calcium carbonate. Created by teachers, our study guides highlight the really important stuff you need to know.

    Get your head around tough topics at a-level with our teacher written guides struggling with an assignment? Learn the basics with our essay writing guide i am going to investigate the rate of reaction between two substances calcium carbonate and hydrochloric acid. The pressure in the gas syringe is built up because of the air-quality of the gas syringe, where it is air tight. Compared to, for example, timing and observation, this method is harder to set up and takes away time which couldve been used to record more results, therefore providing more reliability. These methods were equipment dependent, which is a much more accurate asset than them being human dependent like most of the rejected methods. It is then carefully chopped up into small pieces using a knife and a tile. This method did not prove such reliable measurements and results seeing as the observation would have to be done using human activity, especially eyes instead of a reliable apparatus. Going up and to top hump represents bond breaking on reacting particle collision. As the reaction proceeds, the x gets harder and harder to see because of precipitation taking place. There are numerous ways in which errors have occurred in my experiment, the main reason however is greatly due to heat loss into the atmosphere and the convection of heat into the glass beaker as glass is a poor insulator. Rate of reaction measures the speed at which a reaction takes place.

    Pectinases are a group of enzymes that specifically target pectins, which are polysaccharides that are found in plant cell wall structure. The available methods left are the gas syringe method, and the displacement of water, which compared to the others, turned out to be the most practical, reliable and innovative ways of measurement. This whole method (apart from the flask and part of the tubing) should be carried out in a water tray, full of water. It is supported by clear figures that add to the textual information provided. The gas molecule products produced from the reactants in the flask are transferred from the flask to the gas syringe by the tubing by the movement of gas.

    The tubing should be positioned well on the rear end of the gas syringe Buy now Catalase Gcse Coursework

    The only method left to use is the gas syringe, which appeared to be the most reliable and feasible to set up, as well as being a scientific way of measuring. Place one respectively labelled syringe in each of the test tubes placed in the rack 10. Both come from plants (the papaya and the pineapple) ficin that comes from the fig tree latex is also used for this process. Compared to, for example, timing and observation, this method is harder to set up and takes away time which couldve been used to record more results, therefore providing more reliability. This method is simply done by looking and timing for a particular interval, i.

    This means that there will be more frequent collisions in a shorter space of time Catalase Gcse Coursework Buy now

    However this could only be done with more time in which to carry out the experiment. The displacement of water method provided reliable results, produced by a scientific method. This method is easy to set up and reset, especially compared to a lot of the other methods like the displacement of water and gas syringe. Going up and to top hump represents bond breaking on reacting particle collision. It is dependent on the equipment, which also widens more room for error in the equipment used.

    The only method left to use is the gas syringe, which appeared to be the most reliable and feasible to set up, as well as being a scientific way of measuring. Pectinase is an enzyme and therefore its performance is affected by factors such as temperature, inhibitors and concentration - the factor i have chosen to investigate Buy Catalase Gcse Coursework at a discount

    When particles are heated they take in energy causing them to move faster and collide more often. This means that there will be more frequent collisions in a shorter space of time. Therefore an improvement to this part of the method would be to find a way of emptying the test tube in one go. I will look carefully at the rate of respiration of each substrate during certain times, so after 5 mins, 10 mins etc. However, the set up of the method was the hardest out of all the other methods, and required attention.

    Each enzyme molecule has an active site, where the substrate molecules become attached. The number of marble chips will be kept constant for every experiment. However this could only be done with more time in which to carry out the experiment Buy Catalase Gcse Coursework Online at a discount

    L62 there are 3 ways ph can alter enzyme activity. Pectinases are a group of enzymes that specifically target pectins, which are polysaccharides that are found in plant cell wall structure. In order to find out the volume of all the juice produced by the apple pulp, a will be used to suck out all of the remaining juice and the final volume of the juice will be noted. This method of measurement in products is extremely easy to measure and set up. It is possible to go on and look at the effect of temperature on pectinase and also substrate concentration, however the latter would be fairly difficult to measure.

    Underneath of the flask, an x is marked onto the paper, in the middle. When the temperature doubles, the rate of the reaction roughly doubles Catalase Gcse Coursework For Sale

    It is possible to go on and look at the effect of temperature on pectinase and also substrate concentration, however the latter would be fairly difficult to measure. The calcium carbonate is mixed with the hydrochloric acid in the conical flask. This method works by measuring the loss of mass as a as forms. This means that there will be more frequent collisions in a shorter space of time. They work by the substrate molecule binding with the enzyme to form an enzyme-substrate complex.

    This method is unreliable due to the fact it is dependent on human eye sight, which can never guarantee accuracy. However, unlike timing and observation, this method is far more accurate, so a result or two less would not be much trouble For Sale Catalase Gcse Coursework

    Water is where if you put an element in water, the amount of water displaced (thrown out) is equal to the volume of that element- so by measuring the overflow of water you can work out the volume of the object (it only works if the object is non-porous). . The pectin chain is held together by a bond between carbon 1 of one galacturonic acid and carbon 4 of the next one and so on. However, unlike timing and observation, this method is far more accurate, so a result or two less would not be much trouble. The ph of the solution is also need to be constant at the optimum ph for pectinase.

    This is done until an apple pulp is produced. This whole method (apart from the flask and part of the tubing) should be carried out in a water tray, full of water Sale Catalase Gcse Coursework
