What is the function of the gallbladder?
To make digestive enzymes
To break down food into smaller molecules
To produce bile
To store bile between meals
The Correct Answer is D
A. To make digestive enzymes: the gallbladder stores bile; it does not synthesize digestive enzymes (that’s mainly the pancreas and some glands).
B. To break down food into smaller molecules: mechanical/chemical digestion is done by enzymes and acids; the gallbladder’s role is storage/release of bile, not direct digestion.
C. To produce bile: the liver produces bile; the gallbladder stores and concentrates it.
D. To store bile between meals: the gallbladder concentrates and stores bile and releases it into the duodenum when needed for fat digestion.
