In intestinal epithelial cells, the following conditions exist: a. Na+ concentrations are higher outside of the cell. The Na+ concentration gradient is maintained by the consumption of ATP. b. Amino acid concentration is higher inside the cell. c. Amino acid transporters are membrane proteins that facilitate the transport of amino across the plasma membrane, moving both amino and Na+ into the cell. Based on the facts above, this mechanism is categorized as ______________.

1. Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Na-glucose symporter. Recall that the Na concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Na' ions into the cell to the "uphill" transport of glucose into the cell. (opts) a. If the Na concentration outside the cell ([Na Jou) is 161 mM...

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...

You have isolated the Na/K-ATPase in a semi-purified membrane system. Given higher concentrations of Na' out and higher K inside, addition of ATP to the inside leads to increases of Nat olutside and Kt inside as expected. If instead, you add the ATP to the outside of the membrane, you don't see any change in the ion levels. Why? • ATP acts as an irreversible inhibitor of the Na/K-ATPase if it binds on the exterior side. The active site for...

Many cells take up molecules against their concentration gradients: the molecules are more concentrated inside the cell than outside. Amino acids are frequently transported in this fashion. For the question below, think about intestinal cells growing in medium that is equivalent to blood. The concentration of amino acids is higher in the cell's cytoplasm than in the medium outside the cell. Please indicate whether each of the following modes of transport would permit amino acid uptake into the cell. For...
