function of villi and microvilli (brush border)

large exocrine and endocrine gland
whtàat type of enzymes are digestive enzymes and where do they operate
extracellular enzymes operation in lumen of digestive tract
carbohydrate digestion and enzymes
- polysaccharides hydrolyzed to dissacharides by salivary amylase and pancreatic amylase
- dissacharides hydrolyzed to monosaccharides by sucrase, lactase, maltase in brush border
protein digestion
proteases hydrolyze proteins to aa
