Identify the incorrect statement about enzyme catalysis:

Correct answer: C. It shows maximum rate of reaction at minimum temperature

  • A. It is highly specific in action
  • B. Its activity is increased by the presence of activator
  • C. It shows maximum rate of reaction at minimum temperature
  • D. Its catalytic activity is inhibited by a poison

Explanation

Option C is correct.The incorrect statement about enzyme catalysis is: It shows maximum rate of reaction at minimum temperature. Enzymes are biological catalysts that speed up the rate of chemical reactions in living organisms. They are highly specific in action, meaning that each enzyme only catalyzes a specific reaction. Enzymes are also affected by temperature, with their activity increasing with increasing temperature up to an optimum temperature. Beyond the optimum temperature, enzyme activity decreases due to denaturation of the enzyme .

About Reaction Kinetics

Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
