An investigation to show the effect of temperature on respiration

Extracts from this document...

Introduction

An investigation to show the effect of temperature on respiration Plan The rate of maggots' respiration will be tested at different temperatures. Respiration is a chemical reaction that combines glucose and oxygen to release energy, water and Co . Respiration is important because without it no living organism would be able to survive. This investigation should prove a success if I find out how temperature affects the rate of respiration. A respirometer is a useful piece of equipment that will be used to measure the rate of respiration in the maggots. ...read more.

Middle

How far the dye is drawn up will depend upon the rate of the maggots respiration. The distance the dye has moved will be measured using a ruler and recorded. I am hoping to see the dye move along the tube so I can use this as evidence. My Year 10 notes tell me that as the temperature increases enzyme activity should also increase. At around 40?C enzymes become denatured so the respiration reaction would cease. I believe that as the temperature rises by 10?C the rate doubles. ...read more.

Conclusion

The distance the Eosin dye has moved up the tube in a certain time will be measured. I have selected these temperatures: 0?C, 10?C, 20?C, 30?C, 40?C and 50?C. These temperatures have been selected so that a precise graph can be drawn with an expansive range of results. Each temperature will be repeated twice to eliminate anomalous results. Qualitively I predict that as the temperature increases the rate of reaction will increase due to enzyme activity escalating. Quantitively I predict that with a 10?C rise in temperature the rate will double. The results can be used as evidence in the form of a graph. With a good range of temperatures the results will be accurate. James Noton 10G ...read more.

    * Increasing this factor will increase the rate. * The rate will continue to increase until another factor becomes limiting. * Any further increase in the original factor will now not increase the rate. * With no limiting factors, increasing a factor above a certain level will not increase the rate.

    This will keep my results accurate. There are many possible causes of error that could affect my results: * If the yeast and glucose mixture is not the same temperature of the water. * If the temperature of the water bath (and hence the glucose and yeast mixture)

    Using the 250cm� beaker, measure out 200 cm� of distilled water and place the 10g of yeast into it. Place the buffer tablet into the solution and stir it until it dissolves. This will ensure that the yeast solution is at the optimum pH in order for the enzymes to work effectively.

  1. An investigation into the effect temperature has on the activity of the enzyme catalase ...

    If no water or oxygen is produced then you know that the catalase activity has been stopped. Therefore, to test for catalase activity you can test for the presence of oxygen. I will obtain the enzyme catalase from potato. Variables which have to be kept constant: In my experiment I have to choose the substrate concentration.

  2. Investigating the effect of temperature on yeast respiration.

    After the 5 minutes acclimatisation time, the delivery tube, from the boiling tube containing the yeast will be placed under the burette, to begin the measure of the yeast respiration. I will allow it 10 minutes, I will use this amount of time as it will not be so short

  1. Potato and Osmosis Investigation

    For example if one of the potato tubes were to be one cm longer than the other tubes, the surface area of the tube would be larger so there would be more space for osmosis to occur. To obtain varied results it will be essential to vary the concentration of the sugar solution.

  2. An Investigation to find out how Temperature Affects Respiration in Yeast.

    The range of equipment in the school labs is limited, so this is what I will be using: Before the stopwatch starts, the sealed flask will be placed in the pre-heated water bath before the yeast. This is to allow expansion of the air inside the flask.
