For most neurons, the extracellular concentration of chloride ions (Cl-) is 108 mM, whilethe intracellular concentration of Cl- is 5 mM.If the plasma membrane becomes more permeable to Cl-, would there be Clinflux or Cl- efflux at an RMP of -70 mV? Why?

Many cells in the human body maintain an electric potential difference across their cellular membranes, typically through the use ion-specific pumps and channels that generate an excess of negative charges on the inside of the cellular membrane and an excess of positive charges on the outside. Let us estimate the total energy stored in the human body by this type of charge separation.
Suppose that the concentration of CI outside the cell is 100 and inside the cell is 10 mmol/liter. The Nernst equation at 20°C is: Eton = 58 millivolts/z- [10810 (m)] [lonlin You set the membrane voltage at 0 millivolts using a voltage clamp, and measure membrane current. If Cl is the only ion crossing the membrane, you would expect to see: Onegative charges flowing into the cell negative charges flow out of the cell 0 current the membrane hyperpolarizes (becomes more negative)

What happens across the membrane of an electricallyactive cell is a dynamic process that is hard to visualizewith static images or through text descriptions. View thisanimation (http://openstaxcollege.org/l/dynamic1) toreally understand the process. What is the differencebetween the driving force for Na+ and K+? And what issimilar about the movement of these two ions?
The rapid upstroke of a SA nodal cell action potential is due to the opening of voltage-gated Na+ channels. answer should clearly state whether or not the statement is correct and then concisely explain why. the answer should be 3-5 sentences and address all of the points in the statement. Here is an example: Both transmembrane carrier proteins and transmembrane channel proteins can mediate active transport of a hydrophilic solute through a cell plasma membrane. This statement is incorrect. Movement of a solute through a channel protein is always passive, whereas carrier-mediated transmembrane transport can be either passive or active. A transmembrane channel protein creates a pore through the membrane allowing for simple diffusion of a hydrophilic solute down a concentration gradient through the membrane. In contrast, transmembrane carrier protein interacts with and ‘escorts’ a hydrophilic solute through the membrane and is capable of transporting a solute against a concentration…
Assume that a membrane permeable to Na+ but not to Cl- separates two solutions. The concentration of sodium chloride on side 1 is higher than on side 2. Which of the following ionic movements would occur? a. Na+ would move until its concentration gradient is dissipated (until the concentration of Na+ on side 2 is the same as the concentration of Na+ on side 1). b. Cl- would move down its concentration gradient from side 1 to side 2. c. A membrane potential, negative on side 1, would develop. d. A membrane potential, positive on side 1, would develop. e. None of the preceding is correct.
