GI Flashcards
How are H+ ions pumped back into the GI lumen
Sodium-Proton Exchanger
What enzyme breaks down lipids
Lipase
Product of triglyceride breakdown
Monoglyceride & 2 FA
Bile salt is ampipathic. What does this mean?
It has a polar and nonpolar side that serve to emulsify fat
Composition of bile

What would carbonic anhydrase inhibitor do to H+ secretion
H+ secretion would decrease, decreasing stomach acid production
Somatostatin action on GI secretion
inhibits acid production via Gi pathway released from D cells
What is released by the parietal cells?
