Question
The map of GI tract
2. Draw a simplified map of the gastrointestinal tract including accessory organs. Anatomical portions of the GI tract should be clearly labeled. 3. For each macronutrient (CHO, protein, and fat) indicate the tissue source(s) (i.e., location) of enzymes required for macronutrient digestion. For each enzyme listed you should indicate the specific substrate(s). 4. Also include other digestive secretions (e.g., HCI, bile, etc.) that play important roles in macronutrient digestion. Indicate the source of these secretions and the macronutrients for which they are required. 5. Finally, using arrows, indicate the digestive processes that are stimulated by the gastric hormones gastrin, secretin, CCK, and motilin. In your drawing you should identify the cells types (i.e., specific enteroendocrine cell) and anatomical locations from which these hormones are primarily released. 6. Draw an enlarged version of an enterocyte and indicate the cellular location, name, and substrate for enzymes located within this cell that are required for digestion of macronutrients. 7. Finally, illustrate the form and location of macronutrients that are absorbed across the basolateral membrane of the enterocyte [e.g., glucose (monosaccharide) - ) portal circulation]. As a reminder, recall that lipids are repackaged into chylomicrons (CM) as triacylglycerol (TAG) and secreted into the lymphatic circulation (not the portal circulation).Explanation / Answer
