c. 10 cm3 test tubes, 0.5 cm3 catalase enzyme, 4 cm3 of H2O2, and Certain Temperature (10 degrees C, 20 degrees C, 30 degrees C, 60 degrees C) The test tube is where the dependent variable that is measured. …show more content…

Exergonic Reaction with Catalyst

First, pour about 15 ml of substrate solution into a 25 ml beaker. Then, put the substance in an hot water bath and set it to 30‹C. Next, add a filter paper disk soaked in yeast solution and record the time it takes for the disk to rise to the top of the solution. Repeat steps 2 and 3 2 more times for 30 ‹C and 3 times for 40‹C. Finally place the solution in a ice bath for 20‹C and repeat steps 2 and 3 3 more times. First, pour about 15 ml of yeast solution into a 25 ml beaker. Then, add a filter paper disk soaked only in water in the substrate solution and wait until it sinks to the bottom. Next, add a filter paper disk soaked in substrate solution and it should immediately sink to the bottom. After, record the time it takes for the disk soaked in the substrate solution to rise to the top of the solution. Repeat the 3rd and 4th step 2 more times.

Then the scientist will observe the different rates of reaction with temperature. The Boltzmann distribution of law, indicates that high temperature makes molecules gain high energy contents (pubs.acs.org/doi/abs/10.1021/ja). In order to measure the reaction rate, the scientists must use the same volume of water at three different starting temperatures: hot tap

The effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. About temperature: If the temperature stays the same, then the speed of the enzyme reaction will not be completely affected. Background information: The function of enzymes is to speed up the biochemical reaction by lowering the activation energy, they do this by colliding with the substrate.

There are few vegetables and fruits that turns to the color brown if their surface is exposed to oxygen. Once the veggies or fruits been exposed to oxygen, then the browning begins to appear, and electrons and hydrogen will be removed. This happens because of an enzyme called catechol oxidase. The enzyme will act on its substrate catechol to form a yellow compound which then reacts with the oxygen in the air and change into benzoquinone. The more concentration of the enzyme, the more browning appears.

Using two test tubes, label one “s” for substrate and the other “e” for enzyme. The substrate tube should contain 7 mL of distilled water, 0.3 mL of hydrogen peroxide, and 0.2 mL guaiacol and the enzyme tube should contain 6 mL of distilled water and 1.5 mL of peroxidase. Combine the materials of the substrate and enzyme tubes, mix the two using a clean transfer pipette, transfer a portion into a cuvette so that the cuvette is about half-full then cover the top of the cuvette with Parafilm and then place it in the spectrophotometer and record absorbance. Remove the cuvette and repeat recording absorbance at 1, 2, 3, and 4 minutes. Be sure to mix the cuvette and clean its surface with Kimwipes before each reading.

The Biological Temperature Of Catalase

Introduction: Enzymes are biological catalysts that increase the rate of a reaction without being chemically changed. Enzymes are globular proteins that contain an active site. A specific substrate binds to the active site of the enzyme chemically and structurally (4). Enzymes also increase the rate of a reaction by decreasing the activation energy for that reaction which is the minimum energy required for the reaction to take place (3). Multiple factors affect the activity of an enzyme (1).

The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.

Introduction In class, a series of experiments were performed that pertained to the enzyme known as catalase, which converts hydrogen peroxide into oxygen. Due to peroxide being toxic to the tissues of both plants and animals, both possess the enzyme catalase, which breaks into two non-toxic compounds: water and oxygen gas. Enzymes are proteins that react to certain substrates to create a product, and continue doing so afterwards. Methods and Materials To test reactions between catalase and hydrogen peroxide, groups of three to four people were formed.

Research question What is the effect of temperature Amylase activity? Word count-1453 Background research Enzymes are biological catalysts that speed up a chemical reactions. They do this by decreasing the activation energy(the energy needed to start the reaction) of a chemical reaction. The enzyme present in our saliva is called Amylase. Amylase increases the rate of reaction by decreasing the activation energy needed to hydrolyse the starch molecules.

Bio Chem lab Report 04 Enzyme Biochemistry Group Member: Chan Man Jeun Duncan (16002621) Law Sze Man (16000478) Introduction Enzyme is a protein base structure substance in our body. It works at a biocatalyst that will catalyzing the chemical reaction, which helps to speed up the chemical reaction. Enzyme could only function in specific shape, and the shape of enzyme is depending on the environment, therefore it is hard for an enzyme to function well in an extreme environment. The aim of this experiment is to see can the enzyme functions normally in different environment(pH, temperature and salt concentration) via using starch solution, amylase from saliva, 0.5M HCl solution, 0.5M NaOH solution and NaCl solution, and using iodine solution
