Secretin - inhibits glucagon and insulin secretion
CCK - induces satiety
Show Solution
Verified By Collegedunia
The Correct Option isC
Solution and Explanation
Step 1: Understanding the Concept
Gastrointestinal hormones are produced by the mucosa of the stomach and intestine.
Step 2: Check the pairs
Gastrin stimulates gastric juice secretion.
GIP inhibits gastric secretion and motility.
CCK induces satiety and contraction of the gall bladder.
Step 3: Mismatch
Secretin inhibits gastric secretion and stimulates pancreatic and bile secretion. It does not inhibit glucagon and insulin secretion as stated, so this pair is mismatched.
Final Answer:
The pair secretin - inhibits glucagon and insulin secretion is the mismatch.
\[ \boxed{\text{(C) }\text{Secretin - inhibits glucagon and insulin secretion}} \]
