    Investigation of Enzymes Aim === To find out how enzymes are affected by temperature. ==================================================== Method ------ . Mix starch and amylase together to get a solution . Place it in 6 Beakers . Place this mixture in 6 Electric baths at different temperatures. E.g. 20,25,30,35,40,and 45 . Use a pipette to put 2 drops of the solution at 20oC in a spotting tile . Then add two drops of Iodine (to test if starch is present-the

  • Investigation of Enzymes

    Investigation of Enzymes The majority of the reactions that occur in living organisms are enzyme-controlled. Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage. Without enzymes toxins would soon build up and the supply of respiratory substrate would decrease. Enzymes are proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules of one substrate. The

  • Investigation on Enzymes

    Investigation on Enzymes Introduction Sam and Sarah planned and carried out an experiment to see the effect of pH on the activity of the enzyme amylase which breaks down starch into sugar. They decided to investigate 5 different pH's 2,4,6,8 and 10. 1. The used a measuring cylinder to measure out 5cm3 of starch and placed it in a test tube. They then added acid or alkali until they got to pH2. They checked this using indicator paper 2. They placed the test tube in a rack on the bench

    Enzymes Investigation In this investigation, I will assess how changing the concentration of substrate affects the rate at which an enzyme-catalysed reaction occurs. An enzyme is a biological catalyst. It speeds up a reaction but does not react itself. Enzymes usually catalyse the breakdown of substances into less complex substances. The substance an enzyme acts on is known as the substrate. Each enzyme is specific to one substrate. Enzymes work best in specific conditions of temperature

  • Enzyme Action Investigation

    1632 Words  | 7 Pages

    Enzyme Action Investigation Aim === My aim is to collect sensible results in an investigation to prove the optimum temperature for the enzyme amylase to break down starch. Background info =============== An enzyme is a biological catalyst that breaks down large molecular structures so they can be absorbed easier. It is found in all living things and there are more than 700 known enzymes in existence. However when an enzyme reacts, it remains the same and can continue breaking

  • Investigation on the Enzyme Trypsin

    2374 Words  | 10 Pages

    Investigation on the Enzyme Trypsin An Investigation determining a factor affecting the rate of digestion of gelatin by the protease trypsin. Introduction An enzyme is a biological catalyst, which speeds up reactions. An example of this in the human body is trypsin (a protease produced in the pancreas and used in the stomach), which catalyses the digestion of gelatine, a protein. For this investigation, a photographic film will be the source of the gelatine. I will be able to identify

  • Enzyme Experiment: An Investigation Of The Succinate Dehydrogenase

    1106 Words  | 5 Pages

    An investigation of the enzyme succinate dehydrogenase. Introduction Enzymes are a catalysts that speed up a chemical reaction inside of a cell without being consumed or changed by the reaction. (Wright, W. 2015) Enzymes catalyse reactions by lowering the activation energy that is required for the reaction to occur. (Nature, 2012) In this experiment we will be using Succinate dehydrogenase which is an enzyme that has been extracted from chicken hearts, succinate dehydrogenase is an enzyme of the

  • An Investigation Into The Rate of Reaction of The Catalase Enzyme

    866 Words  | 4 Pages

    An Investigation Into The Rate of Reaction of The Catalase Enzyme Introduction: In this experiment I will attempt to investigate the factors that effect the rate of reaction of the catalyse enzyme. Catalyse is an enzyme found in food such as potato and liver. It is used for removing hydrogen peroxide because of the shape of the hydrogen peroxide molecule; this type of reaction is when a molecule Is broken down into smaller pieces called catabolic reaction. Enzymes are proteins e.g

  • Investigation of Whether Temperature Affects Enzyme Activity

    832 Words  | 4 Pages

    Assessment for DCP and CE Determining if temperature affects enzyme activity This investigation is using a range of temperature in order to find weather or not Temperature affects enzyme activity. I will: 1. Observe the effects of different temperatures on enzyme activity 2. Infer the relationship between the two 3. Use a line graph to display data and draw a conclusion Research Question How does temperature affect enzymes activity? Variables Independent Variable: Temperature

  • Investigation the Factors that Affect Enzyme Controlled Reactions

    435 Words  | 2 Pages

    Investigation the Factors that Affect Enzyme Controlled Reactions Planning In this experiment I am going to try and find out the factors that affect enzyme controlled reactions by using the Catalase in potato. Enzymes are non-living and act as biological catalysts, which speed up reactions. They can change shape if the temperature changes. Enzymes are made up of active sites (the lock) and only certain shaped substrates can fit into them to cause a chemical reaction. To work out this
