Answer:
c. Increasing temperature above the optimal value slows the reaction rate
Step-by-step explanation:
Enzyme activity is affected by factors, such as temperature, pH, and concentration.
The rate of an enzyme-catalysed reaction increases as the temperature increases. However, increasing the temperature above the optimal value slows the reaction rate because the enzyme becomes denatured and can no longer function.
Thus, the correct option is "C"
c. Increasing temperature above the optimal value slows the reaction rate
