Q. 17 - Biology

Question

Which hormone controls the release of bile from the gallbladder 

a. pepsin 

b. amylase 

c. CCK 

d. gastrin 

Step-by-Step Solution

Answer

Option c is the correct answer

Step 1: Introduction

Digestive secretions from the liver, pancreas, and gallbladder are crucial for the intestinal phase's digestion of chyme in the duodenum. Secretin, a hormone, causes the pancreas to create an alkaline bicarbonate solution and transfer it to the duodenum in order to neutralise the acidic chyme.

Step 2: The explanation for the correct option

Secretin works in conjunction with the hormone cholecystokinin (CCK). Thereby, CCK stimulates the gallbladder to discharge bile into the duodenum.

Step 3: The explanation for the incorrect options

As CCK is the one which stimulates the gallbladder to discharge bile into the duodenum, the rest of the options are incorrect and irrelavant.
