Based on the graph, please identify which factor most likely accounts for the change
in the rate of enzyme action as the temperature increases from 40°C to 58°C? (AKS
1a1)((DOK 2)
21
a. Excess acids have been building up, causing the enzyme to become fatigued.
b. Too much substrate is present at these high temperatures.
O c. Not enough substrate is present at these high temperatures
Od. The high temperature causes the shape of the enzyme to be altered.
