Why do enzyme-catalyzed reactions slow significantly at excessively high temperatures?

Select one answer

The enzyme lowers the activation energy to an unfavorable level.

The enzyme's active site becomes more rigid and prevents substrate release.

High temperatures cause an increase in the amount of substrate.

The enzyme denatures, losing its functional shape.
