Question

What are the two routes nutrients take after being absorbed by the small intestine mucosa cells (indicate which is for water loving/hating substances) What are the two places enzymes in the small intestine come from? The system and the system regulate the digestive system. are chemical substances needed by the body for growth, maintenance, repair, and reproduction. Match with the correct definition: proteins Used as an energy source to make ATP. Starch, glycogen, plant fibers are examples. Vitamins Some are used to form solid structures like bone and teeth, examples are iron, calcium, and phosphorus. fats Used as structural support for cells and tissues, also used as enzymes, used for transportation (hemoglobin), and muscle contraction. Carbohydrates Make up a small part of certain enzymes. Fat loving ones we can overdose on. Minerals Used to store energy, insulate our body, cushion internal organs, and create plasma membranes.

Explanation / Answer

12. The two routes are:

A. Transcellular route: nutrients moves across the plasma membrane of the enterocytes cells. Mainly large molecules like amino acids, glucose etc. Active transport method. Polar molecules or hydrophilic molecule takes this route.

B. Paracellular route: nutrient moves between the enterocytes and across the tight junctions. Large molecules like glucose and amino acids cannot pass through tight junctions which takes the transcellular route. Hydrophobic molecules take this route.
