Conditions for Enzyme Action

Q: What is optimum temperature?

A: The temperature at which an enzyme works best.

Q: What is optimum pH?

A: The pH at which an enzyme works best.

Q: What happens if enzymes get too hot or the pH is wrong?

A: They denature (lose shape) and stop working.

Q: What happens if substrate concentration is too low?

A: The reaction is slow.

Q: What happens if substrate concentration is too high?

A: The enzyme becomes saturated, so the rate stops increasing.
