Question

question 13 according to the graph, which statement below is true? relative rate of enzyme activity 0 10 20 30 40 50 60 70 temperature (°c) a this enzyme works equally well at all temperatures. b this enzyme works best at 10 degrees celsius c this enzyme works best at 45 degrees celsius d this enzyme works best at 60 degrees celsius

Explanation:

Step1: Analyze the graph

The graph shows relative rate of enzyme activity versus temperature. The peak of the curve represents the optimal temperature for the enzyme's activity.

Step2: Identify the peak

The peak of the curve occurs around 45 degrees Celsius. This indicates the temperature at which the enzyme has the highest relative rate of activity.

Answer:

C. This enzyme works best at 45 degrees Celsius
