Match each digestive enzyme with its substrate or action.
Answer
Pancreatic alpha-amylase - Breaks starch and glycogen into shorter sugars, Isomaltase - Hydrolyzes alpha-1,6 bonds in limit dextrins, Lactase - Splits lactose into glucose and galactose, Sucrase - Splits sucrose into glucose and fructose
Explanation
### The pairs
| Item | Matches | Why |
|---|---|---|
| Pancreatic alpha-amylase | Breaks starch and glycogen into shorter sugars | It continues polysaccharide digestion in the small intestine. |
| Isomaltase | Hydrolyzes alpha-1,6 bonds in limit dextrins | It removes the branch linkages left by amylase digestion. |
| Lactase | Splits lactose into glucose and galactose | Lactose contains one glucose and one galactose unit. |
| Sucrase | Splits sucrose into glucose and fructose | Sucrose hydrolysis releases these two monosaccharides. |
### Terms
- **Limit dextrin**: A branched remnant formed during amylase digestion.
- **Alpha-amylase**: An enzyme that hydrolyzes starch and glycogen chains.
### Remember
Amylase shortens chains; intestinal enzymes finish specific bond cleavage.
