1. Which of the following will NOT be introduced into the small intestine during digestion?
a. Bile
b. Chymotrypsinogen
c. Chyme
d. Pancreatic lipase
e. Gastrin
Homework Answers
Answer:-e). Gastrin.
The small intestine is where most chemical digestion takes place. Many of the digestive enzymes that act in the small intestine are secreted by the pancreas and liver and enter the small intestine via the pancreatic duct. Pancreatic enzymes ( e.g- Pancreatic lipase , Chymotrypsinogen ) and bile from the gallbladder enter the small intestine to help in digestion.
Chyme is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum of small intestine.
Gastrin is a peptide hormone secreted from stomach primarily responsible for enhancing gastric mucosal growth, gastric motility, and secretion of hydrochloric acid (HCl) into the stomach. Gastrin is primarily released in response to vagal and gastrin-releasing peptide GRP) stimulation secondary to ingestion of peptides, amino acids, gastric distention, and an elevated stomach pH.
