Please can someone help me! I've got to do a biology experiment

to Investigate the relationship between reaction temperature and the effectiveness of action of the enzyme amylase on starch. I really don't know what it is all about pls someone help :)

First, what is your test for the presence of starch? Iodine?

Once you have a test, then start with a standard solution (you decide) of starch, and a standard solution of amylase.

Put your standard solution of starch in test vials. Add the indicator solution.

Now, figure a way to monitor temperature of the vial.

Put your vial in a controlled temp (refrigerator, oven) and raise temp (or lower) by 5C. Then add amalyse, and measure reaction time. Do this for several temps.

Plot reaction time vs temp

Of course, I can help you understand your biology experiment!

The experiment you are referring to aims to investigate the relationship between reaction temperature and the effectiveness of the enzyme amylase on starch. Let's break it down step by step:

1. Background: Amylase is an enzyme that helps break down starch into simpler sugars. It is found in saliva, pancreatic juice, and other places in the human body. This experiment explores how the effectiveness of amylase on starch is affected by changes in temperature.

2. Materials: To conduct this experiment, you will need the following materials:
- Amylase solution
- Starch solution
- Iodine solution (to test for the presence of starch)
- Test tubes or small containers
- Water bath or hot plate to control temperature
- Thermometer
- Timer or stopwatch

3. Procedure:
a. Prepare different water baths or set the hot plate to various temperatures (such as 20°C, 40°C, 60°C, 80°C, and 100°C). These temperatures will act as the independent variable in your experiment.
b. Label your test tubes or small containers with each temperature.
c. Add a specific amount of amylase solution to each labeled container.
d. Prepare a starch solution by mixing starch with water until it dissolves.
e. Add a specific amount of starch solution to each container, immediately starting the timer.
f. Let the reactions proceed for a fixed amount of time (for example, 5 minutes).
g. After the designated time, use iodine solution to test for the presence of starch in each container. Any remaining starch will turn blue/black in the presence of iodine.
h. Record your observations regarding the intensity of blue/black color in each container, representing the effectiveness of the enzyme amylase on starch at different temperatures.

4. Analysis: Once you have conducted the experiment and recorded your observations, you can analyze the results. Consider the following questions:
- Is there a pattern or trend in the effectiveness of amylase on starch with respect to temperature?
- At which temperature(s) was amylase most effective? Least effective?
- How does temperature affect the structure and function of enzymes?

By following these steps, you will be able to investigate the relationship between reaction temperature and the effectiveness of amylase on starch. This experiment helps us understand how enzymes function under different conditions, aiding our understanding of biochemical processes in living organisms. Good luck with your experiment!
