Biology Assignment

Question 1

P1Q: What is the main focus of both graphs in the analysis?

Answer 1

A: The effects of pH on enzyme activity, specifically catalase.
Paragraph 2:

Question 2

P2Q: How does the internet graph measure enzyme activity?

Answer 2

A: By the speed at which the enzyme creates products through reactions.

Question 3

P2Q: How does the student’s graph measure enzyme activity?

Answer 3

A: By measuring the time it takes for a catalase disk to rise.

Question 4

P2Q: Why can these two different measurements be compared?

Answer 4

A: Less time for the disk to rise indicates higher enzyme activity, as catalase breaks down hydrogen peroxide into oxygen faster.

Question 5

P3Q: What is a key difference in the enzymes shown in the two graphs?

Answer 5

A: The internet graph shows three different enzymes, while the student’s graph focuses only on catalase.

Question 6

P3Q: How do the data points differ between the two graphs?

Answer 6

A: The student’s graph has fewer data points, resulting in a less prominent curve for catalase activity.

Question 7

P4Q: What is the pH range difference between the two experiments?

Answer 7

A: The student’s experiment measured pH values between 4 and 10, while the internet graph covered a range from 0 to 14.

Question 8

P4Q: How does the optimum pH for catalase activity differ between the two graphs?

Answer 8

A: In the student’s graph, it peaks at pH 7, while in the internet graph, it peaks at pH 9.
