Practical 2.1- The Effect of Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.

I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then

Matthew Hernandez January 7‚ 2015 Gango – 2 Practice AP Essay In an excerpt from Lady Windermere’s Fan by Oscar Wilde‚ the playwright reveals the values and nature of his own society through the conduct of his characters. The author uses the lives of high-class people to demonstrate the underlying fancies and motivations of the elite society of his time. Wilde targets the society’s emphasis on an external show of good behavior‚ their scorning of the lower classes‚ and their vanity in living for the

Lab Report The effect of temperature on the reaction between Catalase and H2O2 Sarah AlShemesi In this experiment we’ll be exploring the effects of temperature on the reaction between Catalase and H2O2.We’ll be using five different temperatures to test this. The five different temperatures will be 10‚ 30‚ 50‚ 70 and 90 oC. We will use the liver as a source of Catalase. A 1 gram piece of liver will be inserted into a test tube with 2 cm3 of water‚ then 2 cm3 of H2O2 will be added. The Catalase

internal temperature so that the body processes can take place efficiently. The process ensures an equilibrium system is attained for all the body processes. The body temperature of an average individual is 37˚ C. this temperature fluctuates depending on activities one does. A human being is in constant movement unless they are asleep. As such‚ the temperature may increase or decrease thereby varying from this average. Some of the factors that may lead to increase in the body temperature include digestion

Effect of temperature and humidity on the transpiration rateof the whole mushrooms P.V. Mahajan * ‚ F.A.R. Oliveira‚ I. Macedo Department of Process and Chemical Engineering‚ University College Cork‚ Ireland Abstract Water loss or transpiration is an important physiological process that affects the main quality characteristics of fresh mushrooms‚such as saleable weight‚ appearance and texture. A loss in weight of only 5% may cause fresh produce to lose freshness and appear wiltedand it is an

The problem that we are solving is “How does the temperature outside affect the speed and heart rate of the runner?” We chose this to investigate “How does the temperature outside affect the speed and heart rate of the runner?” because we both play sports that require lots of running (Track and Field and Soccer.) Therefore‚ when running track outdoors the weather at the beginning of the meet may be colder‚ than the end when it’s most likely hotter. As well as a soccer tournament‚ you may play a tournament

data. As evident in the table‚ the 10oC temperature is very accurate as the range was 0‚ resulting in an error percentage of 0%. However‚ the 35oC temperature had a no clear skew of results as indicated through the range‚ 14 and the error percentage‚ 161.47%‚ suggesting that the trials at this temperature were not very accurate as they were largely inconsistent. The 50oC also proved to have inaccuracies‚ however‚ not as significant as the previous temperature‚
