SUMMARY
The investigation of pH's effect on amylase activity can be conducted using salivary amylase sourced from saliva, with bread as the substrate. The experiment requires distilled water (pH 7.7), acidic solutions like lemon juice or vinegar, and alkaline solutions to create varying pH environments. To quantify glucose production, iodine solution is utilized, where a blue-black color indicates a positive result. Optimal pH for salivary amylase activity ranges from 6.0 to 8.0.
PREREQUISITES
