Place the following sequential steps of starch digestion in the correct order from ingestion to absorption:
A
Mechanical digestion in stomach → brush-border enzymes in stomach lining → pancreatic amylase secreted into bloodstream and acting systemically before monosaccharide uptake, an inaccurate mix of locations and transport mechanisms.
B
Brush-border enzymes in the mouth → salivary amylase in small intestine → gastric lipase converts starch to monosaccharides → absorption in the stomach, which confuses enzyme locations and substrate specificity.
C
Pancreatic amylase in the mouth → brush-border enzymes in esophagus → salivary amylase in small intestine → monosaccharide absorption in the colon, an order reversing anatomical and physiological sequence.
D
Chewing + salivary amylase → acidic stomach (amylase inactive) → pancreatic amylase in small intestine → brush-border enzymes (maltase/sucrase/lactase) → monosaccharide absorption
