Procedure 1. Place 2mL of milk in each of the 3 test tubes. 2. Heat one of the test tubes to boiling and cool. 3. Add 5 drops of 1% Methylene blue solution to each test tube. 4. Add 2 drops of 1% Formaldehyde to the test tube containing boiled milk and to the other containing unboiled milk leaving the third tube as a control. 5. Mix well. 6. Add 1mL of Paraffin oil to each test tube and warm in a water bath for 10-15 minutes at 40°C. 7. Observe the change that is taking place in each test tube.

Effects of Enzyme concentration on reaction rate. Question: prediction for the effect of enzyme concentration on reaction rate
Write a chemical equation for the reaction catalyzed in model one —— Chemical Reaction I wrote ( Lactase —> Glucose + Galacose ) 1. Referring to the chemical reaction you wrote for the question above is lactase a reactant or product or neither explain how you know. Q2. describe the role of the enzyme lactase played in the reaction. Q3.) what do you think could happen to the enzyme lactase at the end of the reaction Q4.) enzymes play a very specific roles in cells and will work on specific substrates, for example, well liked his breaks down like lactose, lipase is an enzyme that breaks down lipid molecules. Using the base and lactase examples describe how are most enzymes are named. Q5,) suppose a model of a different disaccharide sucrose would like to be able to break down sucrose explain your answer.
Please handraw this graph with all the necessary detailed information: Imagine that I text enzyme rate for four different temperatures: 10 degrees celsius, 20 degrees celsisus, 30 degree celsius, and 40 degree celsius, in separate tubes. The enzyme appears to work faster as temperature increases, but completely ceases activity at 40 degrees celcius. Sketch a graph to show this outcome, but here you will graph product formation (nmoles/mL) vs. time (minutes). The graph should be 4 lines and HANDDRAWN. Include a legend if necessary. You do not need precise quantitivate values, but most show the correct trends on the graph.

Give typing answer with explanation and conclusion If an enzyme was extracted from a mammal versus a freshwater trout from a mountain stream, what differences in functional rage and optimal temperature would you expect?
A biologist investigating enzyme function plotted the activity of a particular enzyme (y-axis) vs pH (x-axis). Experiment A was performed at 30 oC, experiment B at 10 oC and experiment C at 100 oC. Experiments A, B, and C all used the same type of enzyme, they simple tested the enzyme's activity at different temperatures. Using your knowledge of enzyme activity, answer the questions based on the results shown in the graph. (Answer question B) Graph included B. Why is there no hill in the middle of line C?
Below are the results of an experiment to examine the effect of temperature on metabolic rate in mice. Metabolic Rate in Mice at 10°C and 22°C 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 10 degrees C 22 degrees C Chamber Temperature (°C) What is the dependent variable in the experiment? What is the independent variable in this experiment? What is the relationship between temperature and metabolic rate? Metabolic rate (cal/gram/min)
You design an enzyme assay and choose a substrate concentration equal to the Km of the enzymatic reaction. You measure the rate of the reaction at this substrate concentration to be 75.0 μmol/min. Calculate the Vmax of this reaction in μmol/min. Express your answer with one decimal place. Your previous attempt suffered from low signal-to-noise ratio when you used a substrate concentration equal to the Km. So you decide to increase the substrate concentration to 0.45 mM. You remeasure the rate of the reaction at this new substrate concentration and find it to be 135.0 μmol/min. Using the same Vmax value found above, calculate the Km value of this enzymatic reaction. Express your answer in μM with one decimal place. Considering the previous two questions, what would be the rate of the reaction at a substrate concentration of 0.01 mM? Express your answer in μmol/min with one decimal place.
Background information: A static respirometer can be used to measure metabolic rates of small aquatic organisms such as fish and crayfish. The animal is weighed and placed in the chamber. The chamber is then filled completely with water and sealed, and the dissolved oxygen level in the water is measured for 30 – 60 minutes. The animal is then removed and the respirometer is rinsed before being filled with clean water for the next trial. Metabolic rates can be calculated knowing the oxygen consumption rate, the volume of the chamber, and the weight of the animal. The picture shows a typical static respirometer. The probes on the lid measure dissolved oxygen and temperature and are linked to a computer for data collection. When using a static respirometer, the usual procedure calls for filling the chamber completely with water and making sure there is no air left at the top of the chamber when it is sealed. Why is this important, i.e., how would trapped air influence the metabolic…

In the control group, 2 mL of 3% H2O2 was placed in a test tube and a pinch of MnO2 was added. The rate of this reaction was assigned as 5, and the production of bubbles in millimeters (mm) was noted. The reaction was considered complete when no more bubbles were produced. Another control group was set up by placing 2 mL of 3%…
