Temperature significantly affects amylase activity. The optimal temperature for amylase is 37°C, and extreme heat (70°C) causes denaturation. This confirms the lock-and-key model of enzyme function. ✅ – mention diffusion

The results support the hypothesis: 37°C was optimal, as kinetic energy increased collisions between enzyme and substrate. At 10°C, molecules moved slowly, reducing reaction rate. At 70°C, heat denatured the enzyme’s active site, permanently destroying function. A source of error was inconsistent mixing; future experiments could use a spectrophotometer for precise measurement. molecules moved slowly
