• Limit Dextrin Digestion:
• Alpha-amylase cannot hydrolyze $\alpha(1\to 6)$ glycosidic branch linkages in amylopectin, leaving highly branched "limit dextrins".
• Debranching enzymes (isomaltase / oligo-1,6-glucosidase) cleave these $\alpha(1\to 6)$ bonds, ultimately hydrolyzing the branched oligosaccharides into free glucose for intestinal absorption.

Correct option: (3) Glucose

• Taste Receptors in Domestic Chickens:
• The domestic fowl has a rudimentary sense of taste compared to mammals.
• Possesses only $250\text{ to }350$ taste buds (compared to $\sim 9,000$ in humans and $\gt 20,000$ in ruminants).
• Located primarily on the base of the tongue, floor of the pharynx, and palate.

Correct option: (4) 250-350

• pH of Avian Bile:
• In poultry, gallbladder bile is slightly acidic to neutral, with a pH ranging between $5.9\text{ and }6.8$ (approximately $6.0$).
• It neutralizes acidic chyme entering the duodenum from the gizzard, facilitating lipase and amylase activity.

Correct option: (3) 6
