2. Question 2

3. Question 3
   A patient has had their gallbladder removed (cholecystectomy). Which change in digestion is most likely, assuming the liver is functioning normally?

   Loss of intrinsic factor production, impairing vitamin B12 absorptionComplete inability to produce bile, leading to severe fat malabsorptionDecreased secretion of pancreatic enzymes into the duodenumReduced ability to store and concentrate bile, so fat digestion is less efficient after large, fatty meals
