What are 4 enzymes responsible for digestion along with their substrate and end product

4 enzymes responsible for digestion:

1. Salivary amylase substrate: Starch end-product: Maltose  

2. Lipase   substrate: Lipids (fats and oils) end-product: Fatty acids and glycerol

3. Maltase substrate: Maltose end-product: Glucose

4. Protease substrate: Protein end-product: Amino acids

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
