Correct Answer: Bile
✅ Correct Answer: B — Bile
Bile is produced by the Liver and stored in the Gallbladder. When fatty food enters the small intestine (duodenum), bile is released into the duodenum. Bile emulsifies fats, breaking large fat globules into smaller droplets, which increases the surface area for lipase enzymes to act upon, making fat digestion more efficient.
❌ Why other options are wrong:
• A. Pepsin — Pepsin is a digestive enzyme produced in the stomach (by gastric glands) that digests proteins (not fats). It works in acidic conditions.
• C. Trypsin — Trypsin is a proteolytic enzyme (digests proteins) produced by the pancreas; it acts in the small intestine but on proteins, not fats.
• D. Amylase — Amylase is an enzyme that digests carbohydrates (starch to maltose). Salivary amylase works in the mouth; pancreatic amylase works in the small intestine.
📝 Important Note: Bile = produced by Liver, stored in Gallbladder, emulsifies FATS. It is not an enzyme but a digestive fluid. Bile contains bile salts, bile pigments (bilirubin). Removal of gallbladder (cholecystectomy) affects fat digestion. Key SSC CGL digestive system question.
