    Optimum Temperature, pH, and Concentration ABSTRACT Enzymes react differently under different conditions and concentrations, being the most productive at the enzymes specific optimum condition and concentration. The enzyme sucrase, extracted from yeast, breaks down the complex sugar sucrose into the simple sugar glucose. Testing for sucrase’s optimum environment, multiple reactions were ran using varying amounts and concentrations of sucrose and sucrase at different pHs and temperatures. The product

    The Effect of Temperature on the Rate of a Chemical Reaction Aim: In this investigation we are trying to find out how the temperature affects the rate of reaction. Hypothesis: I believe that the higher the temperature, the faster the reaction the reaction between the sodium thiosulphate and hydrochloric acid. This will

    The Effect of Temperature on an Enzyme's Ability to Break Down Fat Aim: To investigate the effect of temperature on an enzyme’s (lipase) ability to break down fat. Hypothesis: The graph below shows the rate increasing as the enzymes get closer to their optimum temperature (around 35 degrees Celsius) from room temperature. The enzyme particles are moving quicker because the temperature increases so more collisions and reactions occur between the enzymes and the substrate molecules

    Investigating the Temperature at Which Soap Powder Will Perform Best At Introduction I am going to conduct an experiment in the controlled environment of a laboratory. The experiment will consist of placing a stained piece of fabric into water with a fixed concentration of a biological washing powder (Wizzo) in it. I will try this experiment several times trying different temperatured water and leaving the it for a fixed period of time to find the best possible temperature that the Wizzo

    To investigate the effect of temperature on the rate of reaction Background Information: Chemical reactions take place all the time at many different rates, some are incredibly fast like an explosion-where you get no time to see what's happening or like rusting which could take years before the iron is completely rusted. The rate of reaction is extremely important because you need to know how long before the end of the session or you may not get results in time. In living organisms

    Investigating The Effect of Temperature on the Structure of an Enzyme Introduction: For my GCSE Biology assessment I will be investigating the enzyme amylase with the substrate starch. This reaction, which I am going to investigate, is called the protein test for starch. Aim: My intention for this observation is to examine how the enzyme catalyses are affected by changes in temperature. Safety Precautions: In this investigation I am going to make sure that everything is as

    The objective of this study was to determine how temperature affects the activity level of the Cepaea nemoralis. Both experiments showed the same relative trend of increased movement in a warm environment as opposed to decreased movement in a cold environment. Both trials had a much greater mean distance travelled over one minute in the warm environment than they did in the cold environment. However, many snails displayed no activity in the cold environment by retracting into their shells and whenever

    The monitoring of body temperature is an essential part of safe, successful nursing care. One of the four major vital signs, it is fundamental in creating a picture of the overall health of the patient (NICE, 2007). Body temperature measurements should be taken as part of the initial assessment and at regular intervals throughout the care and treatment of acute illnesses in adults. The definition of normal body temperature is 37°C, and was first defined as such in the mid 19th century (Sund-Levander

    Temperature and Reaction Time Age and gender of a person have a slight effect of the body`s temperature. Due to the fact as you age your body finds it harder to control the core body temperature, meaning you could be less aware of yourself overheating or have a lessened realization/awareness of a sudden drop in your body's temperature . A newborn baby can also have difficulty with core temperature and could be high one moment and low the next , but after one year the baby ages and starts to develop
