Base your answer on the graph and on your knowledge of biology. What is the most likely result of mixing both enzymes with their substrates in a single test tube?
Understand the Problem
The question is asking to interpret a graph showing the relative rate of enzyme action for gastric protease and intestinal protease at different pH levels. Based on the information, the student needs to determine the most likely result of mixing both enzymes with their substrates in a single test tube.
Answer
Both enzymes would exhibit some activity at pH 5.
The most likely result of mixing both enzymes with their substrates in a single test tube is that both enzymes would exhibit some activity at pH 5.
Answer for screen readers
The most likely result of mixing both enzymes with their substrates in a single test tube is that both enzymes would exhibit some activity at pH 5.
More Information
The graph shows that at pH 5, both gastric protease and intestinal protease have some level of activity, although neither is at its optimal pH. Therefore, both enzymes would likely exhibit some activity.
Tips
Students may misinterpret the graph or misunderstand how pH affects enzyme activity.
