Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for protein

Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

The results of 7 mL water from the front camera in the experiment type 1 is shown in Figure 17. These results were also analyzed with the three different points on the time scale in the same way as the case of 5.5 mL water: that is‚ the first point (A)‚ the second one (B) and the third one (C). According to the three points‚ the graphs from PIV analysis are as well listed with the averaged velocities for 60 frames (30 seconds) and the black vector for only one pair of the frames.

Introduction Enzymes are proteins produced by living organisms to speed up the rate in which chemical reactions occur. This process can happen fast‚ slowly‚ or stop the chemical reaction all together depending on the temperature‚ pH and concentration. Catalase is one of the most common enzymes. It is found in living organisms and is used to break down hydrogen peroxide. This must happen because hydrogen peroxide is considered toxic to cells in the body. However‚ when catalase is used it breaks

Chemistry Unit 1 – Revision Questions Chemistry 1A 1) Define an element. How many are there in the Periodic Table? 2) Write a table with the charges and masses of protons‚ neutrons and electrons. 3) Define atomic number and mass number. 4) Draw electron (energy level) diagrams for Be‚ S‚ Al‚ Cl and K. Also‚ write down the number of protons and neutrons for each. Finally‚ write the symbols (with mass no. and atomic no.) 5) Why have all Group 7 elements (halogens) got similar chemical properties

Enzymes play a vital role in helping our body function. They act as biological catalysts and help speed up reactions that would otherwise take long periods of time to naturally occur. Enzymes help lower the activation energy required for the reactants to reach the transitional state from which then they can form products. However‚ enzymes do not change the free energy of the reaction. Enzyme’s ability to catalyze reactions comes from the shape of the active site on the enzyme. Enzymes are hyper-specific

pH Levels and Temperature Water is very important in life. Without water‚ nothing could survive. Water needs to be clean to drink. People all over the world are using filters to clean and purify water. The best type of filter‚ out of dirt‚ cloth‚ and grass‚ is the grass filter (Allen). The grass filter is completely natural‚ therefore it cleans and purifies the water the best. Does a grass filter affect the pH level and temperature of lake and stream water? The temperature of water affects how solubility

Lab 6.C Hypothesis: If enzyme activity is affected by the pH of a solution‚ then the enzymes will experience the greatest activity at a pH of 6. Variables: Independent Variables Dependent Variable Controls Four different pH values (10‚ 7‚ 6‚ and 3) Change in color of the solution The amount of potato extract‚ pH solution‚ and catechol used (1 cm +/- .1cm) Size of the test tubes Amount of time allowed for the catechol to sit with the potato extract and pH solution (20 minutes with 5

Experiment 5: Percent Water in a Hydrated Salt Chemistry 1300 Instructor: 2/8/12 Abstract: The purpose of this experiment was to determine the percent by mass in a hydrated salt‚ as well as to learn to handle laboratory apparatus without touching it. The hydrated salt‚ calcium carbonate‚ was heated with high temperature to release water molecules. Gravimetric analysis was used in this experiment to determine the percent by mass of water in a hydrated salt. The hypothesis of this experiment

My experiment was to find out how the type of liquid can affect the amount of drops that can fit on a penny. I used 3 liquids to test my question and they were water‚ rubbing alcohol‚ and vegetable oil. I discovered that water could hold the most drops and vegetable oil and rubbing alcohol could hold about the same amount of drops. My hypothesis was if I use water then it will hold more drops than vegetable oil. My hypothesis was supported by my data. The average number of drops for water was 93
