(ii) fat? _____________________________________________________

Explanation / Answer
(i) The pancreatic secretions neutralize the acid content of digestive juices (in chyme) by secreting more bicarbonate ions.
(ii) The fats present in chyme are digested by pancreatic lipase present in panreatic secretions. If more lipids are present in the food, more pancreatic lipase will be produced.
