Which of the following is NOT true of carbohydrate absorption? a. End products of carbohydrate digestion are transported through
the portal vein to the liver. b. Disaccharides are digested to monosaccharides by enzymes attached to intestinal cells. c. Monosaccharides can enter the villi. d. Lactose is absorbed intact and transported through the portal vein to the liver.
Lactose is absorbed intact and transported through the portal vein to the liver.
Explanation:
Lactose are larger molecules which are categorized as the carbohydrates, and have the human system has the basic requirement of such materials in order to survive in a given time. They are not absorbed or passed through the portal vein to the liver.
D. Lactose is absorbed intact and transported through the portal vein to the liver.
Explanation:
Lactose is a disaccharide. It is a sugar composed of galactose and glucose subunits and has the molecular formula C₁₂H₂₂O₁₁. Lactose as a disaccharide can never be absorbed just like that. It needs to be broken down into monosaccharides first.
As Na and Cl make up much of the dissolved common salts found in the ocean waters, the element in the earth's crust can be easily be dissolved in the rain and river and get carried away from the runoff of the river.
Infiltration is process by which water on the ground enters the soil. The porosity of the soil particles on land water determine the infiltration capacity and thus are a major source of dissolved sediments in water bodies.
Also, rainfall influences this rate of sediment flows in water all the organic and inorganic matter in the soil is mainly composed and collected from the rain and discharge rate of the soil. Weathering produces mass wasting and erosion of the landforms from the above and thus indirectly related to the dissolved content.
