QuestionSBA
QuestionChoice
This is the type of pancreatic juice produced via the action of the hormone secretin, which is secreted from ductal cells in the duodenum in the presence of highly acidic chyme. CCK release into the small intestine is triggered by chyme-containing fat and protein products. Once released, it then stimulates the acinar cells of the pancreas to release enzyme-rich pancreatic juice into the duodenum in order to digest the fat and protein within the chyme.

b
High-volume, HCO<sub>3</sub><sup>-</sup> rich, low-enzyme pancreatic juice
QuestionChoice
Whilst the pancreatic juice produced via the action of CCK is enzyme-rich in order to digest the protein and fat present within the chyme, it is not HCO<sub>3</sub><sup>-</sup> rich - as the chyme is not acidic and thus does not require neutralisation. HCO<sub>3</sub><sup>-</sup> rich pancreatic juice would be secreted in response to the hormone secretin.

c
Low-volume, HCO<sub>3</sub><sup>-</sup> rich, enzyme-rich pancreatic juice
QuestionChoice
CCK release into the small intestine is triggered by chyme-containing fat and protein products. Once released, it then stimulates the acinar cells of the pancreas to release enzyme-rich pancreatic juice into the duodenum in order to digest the fat and protein within the chyme.

a
Low-volume, enzyme-rich pancreatic juice
QuestionChoice
CCK does produce enzyme-rich pancreatic juice in order to digest protein and fat in chyme with high protein and fat content. However, much lower volumes of pancreatic juice are produced in response to CCK in comparison to other triggers, such as secretin.

e
High-volume, enzyme-rich pancreatic juice
QuestionChoice
Pancreatic juice should be alkaline in nature in order to neutralise acidic gastric acid. CCK causes release of low-volume, enzyme-rich pancreatic juice in order to digest protein and fat in chyme with high protein and fat content.
