- A chemical called ouabain inhibits the Na/K ATPase (the sodium-potassium pump). What would happen to glucose concentrations in the extracellular fluid (not the gut lumen) after exposure to ouabain, and why? Ouabain would cause intracellular sodium levels to rise, which would reduce the active transport of glucose from the gut, thereby decreasing glucose in the extracellular fluid. Ouabain would cause extracellular sodium levels to rise, which would reduce the active transport of glucose from the gut, thereby decreasing glucose in the extracellular fluid. Ouabain would cause intracellular sodium levels to rise, which would reduce the active transport of glucose from the cell to the extracellular fluid. Ouabain would cause intracellular sodium levels to rise, which would enhance the active transport of glucose from the gut, thereby increasing glucose in the extracellular fluid.arrow_forwardReceptors for chemical messengers are proteins or glycoproteins located either inside the cell or, much more commonly, in the plasma membrane. The binding of a messenger by a receptor manifests specificity, saturation, and competition?arrow_forwardA patient is on a drug for a long time ("LKM A").

Which of the following mechanisms does not count as a regulatory mechanism? a) Buffer system b) Lung compensation c) Gastric acid secretion d) Kidney compensationarrow_forwardYou’ve just come from your annual physical and are alarmed to find that you’ve developed a number of plaque blockages in your coronary arteries. Which intervention might decrease your risk of having a heart attack? (A) Take a drug that reduces the recycling of LDL receptors back to the cell surface.(B) Drink more alcohol, as ethanol has been shown to increase the synthesis of SREBP. (C) Increase your intake of fish to increase your circulating HDL levels.(D) Increase your intake of red meat to increase your circulating LDL levels.(E) Take a drug that decreases the KM of HMG-CoA reductase for HMG-CoA.arrow_forwardWhy is bulk transport important to cells?

- Which of the following happens if the concentration of potassium in the extracellular fluid increases too much?A) Potassium would be taken up by the oligodendrocytes, so no net change in signaaaling would result. B) No signaling could occur. C) The Neuron would become hyperexcitable D) The sodium pumps would immediately fix the situation, so no net change in signaling would result.arrow_forwardWhich of the following statements is false? Question 11 options: a) Nucleotides and amino acids can act as extracellular signal molecules. b) Some signal molecules can bind directly to intracellular proteins that bind DNA and regulate gene transcription. c) Some signal molecules are transmembrane proteins. d) Dissolved gases such as nitric oxide (NO) can act as signal molecules, but because they cannot interact with proteins they must act by affecting membrane lipids.arrow_forwardWhich of the below is likely a substrate of a kinase?
