What types of transport (primary active, secondary active, facilitated diffusion, or passive diffusion) are responsible for amino acids movement through the apical and basolateral membranes of the intestine?
Sri K.
Almost all absorption takes place in the (large? small?) intestine. Absorption is a two-step process. Products of digestion must first be absorbed into (blood or lymph capillaries? epithelial cells lining the intestine?) and then be transported into (blood or lymph capillaries? epithelial cells lining the intestine?). b. Glucose and some amino acids move across the brush border into epithelial cells lining the intestine by (primary? secondary?) active transport coupled with active transport of Fructose enters epithelial cells by (diffusion? facilitated diffusion?). All simple sugars then cross the basolateral surface of the epithelium to enter capillaries by the process of c. Simple sugars, amino acids, and short-chain fatty acids are absorbed into (blood? lymph?) capillaries located in the intestinal wall. These vessels lead to the vein and then to the for storage or metabolism. d. Long-chain fatty acids and monoglycerides first combine with salts to form (micelles? chylomicrons?). This enables fatty acids and monoglycerides to enter epithelial cells in the intestinal lining and soon enter lacteals leading to the (portal vein? thoracic duct?). Most bile salts are ultimately (eliminated in feces? recycled to the liver?). This cycle is known as circulation. e. Aggregates of fats coated with are known as chylomicrons. After traveling through lymph and blood, chylomicrons reach hepatocytes in the or are stored in where triglycerides are reformed.
