A. It speeds up the reaction.
B. It slows down the reaction.
C. It has no effect on the reaction.
D. It stops the reaction completely.
Answer: B. It slows down the reaction.
To answer these questions correctly, you will need to run the simulation and observe the results. Follow these steps:
1. Set the simulation settings as given:
- Starch: 3
- Amylase: 0
- Temp: 35
- Maltose: 0
- Maltase: 3
- pH: 7
- Glucose: 0
- Amylase Inhibitor: 0
2. Run the simulation and observe the results to answer question 4. Based on the options provided, select the correct response that matches your observation. In this case, you need to select "Starch was not broken down by the maltose enzyme."
3. Now, adjust the simulation settings as given:
- Starch: 3
- Amylase: 2
- Temp: 35
- Maltose: 0
- Maltase: 0
- pH: 7
- Glucose: 0
- Amylase Inhibitor: 0
4. Run the simulation again and observe the results to answer question 5. Select the correct response based on your observation. In this case, you need to select "Amylase did not have a reaction with starch."
5. Based on the observations from the first two simulations, answer question 6. Select the response that best represents a logical conclusion. In this case, the correct response is "Enzymes are specific to a substrate."
6. To answer question 7, run the simulation with the given settings:
- Starch: 3
- Amylase: 2
- Temp: 35
- Maltose: 0
- Maltase: 0
- pH: 7
- Glucose: 0
- Amylase Inhibitor: 0
Observe the results carefully and select the correct response based on your observation. In this case, you need to select "Starch was broken down to glucose then, maltose."
7. Now, reset the simulation and set the following settings:
- Starch: 3
- Amylase: 2
- Temp: 35
- Maltose: 0
- Maltase: 2
- pH: 7
- Glucose: 0
- Amylase Inhibitor: 0
8. Run the simulation for about a minute and answer question 8. Select the response that accurately represents what happened during this simulation. In this case, the correct response is "False – All starch was converted into maltose and then glucose."
9. Reset the simulation and set the following settings:
- Starch: 0
- Amylase: 5
- Temp: 35
- Maltose: 0
- Maltase: 0
- pH: 7
- Glucose: 0
- Amylase Inhibitor: 0
Now, adjust the pH by making the solution more basic and more acidic until all of the enzymes are denatured. Repeat this process by running the simulation and adjusting the pH until the enzymes are denatured. Finally, select the correct pH values that resulted in denaturation of all amylase from the given options. In this case, the correct response is "5.5 and 7.5."
I hope this helps you answer the questions accurately! If you have further questions, feel free to ask.
