#28) A trypsin antagonist is present during fat metabolism. Which of the following processes will NOT occur?
A. Emulsification of fats
B. Increase in fat content in the small intestine
C. Hydrolyzation of fat deposits in the small intestine
D. Decrease in CCK production
Alright I understand why C is correct. No trypsin = no PL activation = no fat hydrolyzation. But wouldn't this also mean an increase in fat content (B, which must be correct), and therefore an INCREASE in CCK production? This means that D would also NOT occur. You have an increase in CCK.
#30) Sprue, a disorder of malabsorption in the small intestine, is characterized initially by the increase soap-like appearance of fat in the stools. Which of the following reasons could lead to this symptom?
A. Decrease in chylomicron production
B. Decrease in bile salt secretion
C. Decrease in intestinal microvilli
D. Increase in pancreatic lipase
I chose B. Why? Decrease in bile salts means no cholesterol processing, and a decrease in fat absorption. This would lead to lots of cholesterol and fat in the stool.
They say the answer is C, which is also understandable, but they don't explain why B is incorrect. I have a hard time understanding why B is not the better answer.
