Lipids are not water soluble so they make coat when reach our stomach. In stomach it get hydrolyse by gastric lipase. Then the bile salt form a surface monolayer. The pancreatic lipase broke the lipid into fatty acid. Then the small droplets of fatty acid enter the enterocytes.
Fatty acids are transferred from the lumen of the small intestine to the epithelial cells of...
Based on the figure, describe the mechanisms of uptake of
amino acids from the intestinal lumen into an intestinal cell and
then from the intestinal cell to the bloodstream.
Your answer should include the following terms: primary active
transport, secondary active transport, electrochemical gradient,
concentration gradient, facilitated diffusion, energy.
Question 2. The image below depicts the transport mechanisms used by your intestinal cells to absorb amino acids from your food into your bloodstream. Nat Intestinal lumen Amino acid Nat Amino...
The Na glucose symporter transports glucose from the lumen of the small intestine into cells lining the lumen. Transport of 1 glucose molecule is directly coupled to the transport of 2 Nations into the cell. 2 Na*(out) + 1 glucose(out) - 2 Nat(in) + 1 glucose(in) Assume the following conditions at 37 °C: [Nalin - 12 mm, [Na lout = 145 mm, (glucoseJout = 28 pm, and Ay =-72 mV (inside negative). Faraday constant F = 96,485 C/mol, ideal gas...

1) Glucose enters human enterocytes (intestinal epithelial cells) against its concentration gradient. A Na+ ion enters the cell with each glucose molecule, and while the glucose transporter does not hydrolyze ATP, it depends on a pre-existing gradient of Na+ ions that is created by the Na+/K+ ATPase. This is an example of ____________. A. primary active uniport B. secondary active antiport C. primary active symport D. secondary active symport 2) Which statement is FALSE? A. Acetyl CoA is oxidized to...
