✅ – a negative control (no enzyme) and positive control (known active sample).

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. biologjia 11

✅ – measurement precision, temperature fluctuation, contamination. This confirms the lock-and-key model of enzyme function

Amylase is an enzyme that breaks down starch into maltose. Enzymes are proteins that function best at an optimal temperature. In humans, amylase works best at 37°C. This experiment tests the hypothesis: Increasing temperature up to 40°C will increase the rate of starch breakdown, but temperatures above 60°C will denature the enzyme, reducing activity.
