Which combination accurately lists a major pancreatic secretion and its primary digestive role in the duodenum?

• A. Bile pigments — produced by the pancreas to solubilize proteins and are the primary neutralizing agent for chyme; amylase — degrades lipids primarily into glycerol.
• B. Hydrochloric acid — secreted by the pancreas to activate pepsinogen in the duodenum; cellulose synthase — digests complex carbohydrates into monosaccharides; lipase — emulsifies fats similar to bile salts
• C. Intrinsic factor — added by the pancreas to allow immediate absorption of vitamin B12 in the duodenum while proteases also act mainly to polymerize amino acids for absorption.
• D. Bicarbonate — neutralizes acidic chyme; pancreatic amylase — digests starch; pancreatic lipase — digests triglycerides; proteases — digest proteins

Answer: (D)
