The graph illustrates the relative activity levels of three common digestive enzymes, where 0 represents no activity and 12 represents the highest level of activity. Which enzyme is most active at a neutral pH of 7?
To determine which enzyme is most active at a neutral pH of 7 using the given graph, you need to identify which enzyme has the highest activity level at that pH point.
1. Examine the x-axis of the graph to identify the pH values represented.
2. Locate the point on the x-axis where the pH value is 7, which represents a neutral pH.
3. Look at the y-axis of the graph to determine the activity levels of the enzymes at pH 7.
4. Identify the enzyme with the highest activity level at pH 7.
By following these steps, you will be able to identify which enzyme is most active at a neutral pH of 7 based on the given graph.
