Cell Bioloogy: What will happen to the action potential in cells exposed to considerably higher concentration of Na+?
Homework Answers
Sodium ions plays a considerable role in action potential. The ionic concentration of sodium determines the magnitude of action potential and how quickly it occurs. When extracellular concentration of sodium ion increases action potential starts increasing and tends to occur faster. The higher extracellular concentration leads to concentration gradient between inside and outside of cell. Therefore sodium ion move in to cell more easily. This sodium influx contributes to higher peak of action potential.

5/2400 Resources Give Up Hint Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Nat-glucose symporter. Recall that the Nat concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Nations into the cell to the "uphill" transport of glucose into the cell. If the Na+ concentration outside the cell (INa1.) is 151 mM and that inside the cell ([Na]) is 23.0 mm, and the cell...

HW 11-1 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. If the Na + concentration outside the cell ( [ Na + ] out ) is 149 mM and that inside the cell ( [ Na + ] in ) is 19.0 mM, and the cell potential is −...

when a bear is exposed to radiation, some of its cells can develop mutations in their DNA. If an adult bear's cell in G, is exposed to radiation, what is most likely going to happen to that cell? a. How might this impact the bear's future health? 8. If an adult bear's call that is dividing to become new skin cells or new lung cells is exposed to radiation and picks up mutations in its DNA, what could happen to...

During the propagation of an action potential, what would be the effect of a mutation in the voltage-gated Na+-channels that does not allow “inactivation” phase to occur, such that these channels go directly from open to closed conformations? a) The neuron with the mutant Na+ channels will start letting in calcium ions and generate a calcium-based action potential that is stronger than the sodium-based action potential. b) The neuron with the mutant Na+ channel will exhibit a reverse electrochemical gradient...
