Testing pH of Saliva and Digestive Enzymes – Role of amylase

Saliva pH and Amylase Activity

Testing pH and Digestive Enzyme Function

Investigate how saliva pH affects amylase activity in breaking down starch. Test different conditions and observe the chemical reactions.

Current Step:

Select a pH condition and click "Start Experiment" to begin.

Key Concepts:

Salivary amylase: Enzyme in saliva that breaks down starch into maltose
Optimal pH: Amylase works best at pH 6.7-7.0 (neutral)
pH effects: Extreme pH denatures the enzyme, stopping its function
Iodine test: Detects starch (blue-black = starch present, yellow = starch digested)
