Question

trypsin is an enzyme that catalyzes protein digestion in the small intestine. based upon the two graphs, what is the best temperature and ph for trypsin activity?
37°c and a ph of 8
37°c and a ph of 10
59°c and a ph of 8
59°c and a ph of 10

Explanation:

To determine the best temperature and pH for trypsin activity, we analyze the two graphs. The pH - activity graph shows the peak (maximum activity) around pH 8. The temperature - activity graph shows the peak (maximum activity) around 37°C. Now we check the options:

• Option 37°C and a pH of 8: Matches the peak values from both graphs.
• Option 37°C and a pH of 10: The pH graph's peak is at pH 8, not 10, so this is incorrect.
• Option 59°C and a pH of 8: The temperature graph's peak is at 37°C, not 59°C, so this is incorrect.
• Option 59°C and a pH of 10: Both temperature and pH values do not match the peaks from the graphs, so this is incorrect.

Answer:

A. 37°C and a pH of 8
