Trace the correct sequence for starch digestion from the mouth until absorption in a healthy person:

• A. Brush border enzymes begin in the stomach → salivary lipase completes digestion in the colon → pancreatic proteases absorb monosaccharides
• B. Pancreatic lipase begins starch digestion in the duodenum → bile converts starch into amino acids → salivary amylase absorbs them in the stomach
• C. Pepsin from the stomach converts starch to glucose which is absorbed in the ileum without need for pancreatic enzymes
• D. Salivary amylase begins starch breakdown in the mouth → pancreatic amylase continues digestion in the small intestine → brush border enzymes finish conversion to monosaccharides for absorption across enterocytes

Answer: (D)
