What is effect of temperature?Show answer
As temperature increases from low values, the rate of an enzyme-controlled reaction rises. This is because the enzyme and substrate molecules gain kinetic energy and move faster, so they collide more often and more substrate fits into active sites.
What is q1?Show answer
Define the optimum temperature of an enzyme. [1 mark]
What is q2?Show answer
Explain why the rate of an enzyme reaction increases as temperature rises toward the optimum. [2 marks]
What is q3?Show answer
Explain what happens to an enzyme above its optimum temperature. [2 marks]
