Question

based on the information in the graph, what can be determined about the activity of these enzymes? enzyme b will react only at ph 7. each enzyme will react at all ph levels. enzyme c is most active at a neutral ph. each enzyme is active within a certain ph range.

Explanation:

Enzymes have optimal pH - ranges for activity. They are not active at all pH levels, and most do not have a single, exclusive pH for activity. A neutral pH is 7, but we can't assume Enzyme C's optimal is exactly 7 without the graph. So, it's most accurate that each enzyme has a specific pH - range for activity.

Answer:

D. Each enzyme is active within a certain pH range.
