Question

1. lab 8.1: how do you think changes in ph would affect catechol oxidase activity?
2. lab 8.2: draw a flowchart of the procedure you will be completing during this lab. to learn how to do this watch this video.
3. take a picture of the hand - drawn flowchart or upload a screenshot or image if you have completed it digitally. you may use word document or powerpoint to do so.
4. upload your picture to this discussion post then answer this question: what was the purpose of incubating the content of the tubes separately at different temperatures before mixing them together in the experiment?
5. lab 8.3: lactose, starch and beans starch are all polymers of glucose. explain the purpose of this experiment and the outcome you expect to see.

Explanation:

3.

Enzymes like catechol oxidase have an optimal pH. Deviations from this can denature the enzyme or affect its active - site structure, thus changing its activity.

Incubating tube contents at different temperatures before mixing allows for studying the effect of temperature on the reaction components independently. It helps in isolating the temperature - dependent effects on the substances in the tubes.

The experiment likely aims to study the properties of these glucose polymers. The expected outcome could be differences in reactivity, solubility, or other characteristics based on their polymer structures.

Answer:

Changes in pH can either increase, decrease, or have no effect on catechol oxidase activity. Below or above the optimal pH, the enzyme may denature, reducing its activity. At the optimal pH, the enzyme shows maximum activity.

Since no details about the lab procedure are given, a general flowchart structure could be:

1. Start
2. Gather materials
3. Prepare samples
4. Perform reactions
5. Measure results
6. End

5.

This is a task - based instruction to take a picture or upload a digital image of the flowchart. No specific answer can be provided without actually creating and capturing the flowchart.
