Question

Which of the following conclusions can be drawn from this graph?

Answer 1

Answer:

A

Explanation:

We can't see the graph, but I think I found the worksheet online, and so the graph is attached.

The answer cannot be B, as we are looking at a graph of pH, not temperatures. Therefore, we cannot draw this conclusion

The answer cannot be C, as pepsin is a digestive enzyme, and it works best at pH of around 2.

The answer cannot be D, because we can see that arginase and salivary amylase work at pH 7 and above, which is not acidic

The answer is A, because the lines for each enzyme are different, each peaking at a different pH. These peaks represent their optimum temperatures, and the hills of the peak represent the range in which they can work
