Final answer:
Dextrinase, lactase, and sucrase are small intestine brush border enzymes participating in carbohydrate digestion.
Step-by-step explanation:
The small intestine brush border enzymes participating in carbohydrate digestion are dextrinase, lactase, and sucrase. These enzymes are present in the brush border of the small intestinal wall. Dextrinase breaks down a-dextrin into glucose, lactase breaks down lactose into glucose and galactose, and sucrase breaks down sucrose into glucose and fructose.
