Enzyme rate peaks at an optimum temperature, then drops sharply because
- A
Cold denatures the enzyme, freezing its active site
- B
High temperature destroys the substrate's binding region
- C
Heat increases substrate diffusion, overwhelming sites
- Dcheck_circle
Heat denatures the enzyme, disrupting its 3D shape
Explanation
Past the optimum, weak interactions holding the active site unravel; the enzyme loses its specific shape and activity.
