8-Potassium ions: a- Predominate the extracellular medium of the neuron b-Predominate the intracellular medium of the neuron c-Are found only inside the neuron d-b & c e-None of the above

Homework Answers

Answer #1

The right option is option (B) Predominate the intracellular medium oh the neuron

Explanation :-

The concentration of Potassium is around 140mmol/l inside the cell while outside the cell, it is around 6mmol/l. Thus, potassium concentration is higher inside the cell. This is opposite to Sodium which is found higher outside the cell and lower inside. This concentration gradient is responsible for the generation of membrane potential and nerve impulses are carried out due to this.

5) A new drug has been discovered that completely opens the voltage-gated potassium channels. If this drug is used experimentally on an isolated axon, the membrane potential can be easily measured. Assume that this experiment provided the following results. The extracellular Na+ is 145 mM and the extracellular K+ is 4mM, the measured membrane potential in the presence of the drug is -94mV. Using this information, calculate the intracellular K+ concentration. To solve this equation, you will need to use...
