Question

role of various digestive enzymes

Answer 1

digestive enzymes are helpful for the digest the food

Answer 2

The foremost function of digestive enzymes is to breakdown larger food materials into smaller food particles so that helps in absorption of food particles

These enzymes are secreted by parts of digestive tract

These are mainly

Salivary secretion
Gastric secretion
Pancreatic secretion (mainly exocrine part )
Bile secretion
5 .Intestinal secretions (mostly small intestine )

The main food uptake of humans is mostly

macronutreints (carbohydrates ,lipids,proteins)Micronutrients(vitamins ,minerals)

These are mostly absorped with the help of digestive enzymes

These are secreted unconditionally mostly by seeing or smell of food eg :saliva secreted by even smell of some food

And some are secreted only after food is ingested eg:pancreatic secretion {pancreatic amylase} secreted after food enters the stomach
