Question
1. For most neurons, the extracellular concentration of chloride ions (Cl-) is 108 mM, while
the intracellular concentration of Cl- is 5 mM.
a. If the plasma membrane becomes more permeable to Cl-, would there be Clinflux or Cl- efflux at an RMP of -70 mV? Why?
Can this be explained step by step please and may I have the answers types thank you! (::
Expert Solution
Step 1
Neurons are the structural and functional units of the nervous system. These cells are specialized in perceiving and transmitting the stimulus in the form of electrical impulses. At rest, the interior of these neurons is more negative (or less positive) than the exterior and hence it possesses a resting potential of -70 mV.
