Question

Explain why bile juices does not contain any digestive enzymes yet it is essemstial for digestion

Answer 1

Bile juice contain bile salts which break the fats into smaller globules which increases the efficiency of enzyme action so therefore it is essential for digestion

Answer 2

Bile juice creates an alkaline medium for the pepsin to act on proteins { HCl in the stomach had earlier activated the pepsinogen to pepsin} and convert  them  to amino acids. Bile salts also break up larger fat globules into smaller globules ( emulsification ) so that they can be acted upon by the pancreatic juice's enzyme lipase, which will  convert them into fatty acids.
