alleryBile DOES NOT contain any digestive enzyme, yet it AIDS in digestion of fats because it:
AConverts fats to amino acids
BNeutralises stomach acid
CHeats the food
DEmulsifies fats (breaks into smaller droplets)
Answer & Solution
Correct answer: D. Emulsifies fats (breaks into smaller droplets)
1. Bile contains bile SALTS (no digestive enzymes).
2. The salts emulsify large fat globules into smaller droplets, increasing surface area for lipase.
3. Lipase (from pancreas) then breaks the fats into fatty acids and glycerol.
4. Bile also helps neutralise gastric acid entering the duodenum (function 2).
