Answer #1

Human nerve cells work mainly on the concept of membrane potentials. They transmit chemicals known as serotonin or dopamine through gradients. The brain receives these neurotransmitters and uses it to perform functions.

  • Na+ has a much higher concentration outside of the cell and the cell membrane is very impermeable to Na+
  • K+ has a high concentration inside the cell due to the fact that the cell membrane is very permeable to K+
  • A- is used to refer to large ions that are found completely inside of the cell and cannot penetrate the cell membrane.

1. A cell membrane with a total conductance of 45 nS is injected with a current of 4 nA. The length constant of the membrane is 2.0 mm. The magnitude of the depolarizationmeasured 2.5 mm from the point of injection and recorded 1.0 ms after the beginning of the injection is 1.5 mV. Knowing that the depolarization depends on the distance from the point of injection, x, as given by the formula below, calculate the total capacitance of the cell...

Explain the transport cycle of the sodium-potassium ATPase. How does it contribute to the resting membrane potential of a neuron? What would happen to the concentration of sodium and potassium inside and outside of the cell if you inhibited sodium-potassium ATPase transport with a drug? Would it be possible for an action potential to occur if the sodium-potassium ATPase were inhibited? Why or why not?

2. The portion of a nerve cell that conducts signals is called an axon. Many of the electrical properties of axons are governed by ion channels, which are protein molecules that span the axon’s cell membrane. When open, each ion channel has a pore that is filled with fluid of low resistivity and connects the interior of the cell electrically to the medium outside the cell. In contrast, the lipid-rich cell membrane in which ion channels reside has very high...

Select the statements that describe the operation of the sodium–potassium pump. (More then one statement is correct) The sodium–potassium pump transports sodium and potassium down their concentration gradients. For every two sodium ions pumped out of the cell, three potassium ions are pumped into the cell. For every exchange of sodium and potassium ions, one ATP molecule is hydrolyzed. The sodium–potassium pump actively transports ions across the membrane, which maintains homeostasis.

18. Assume the resting membrane potential of nerve cell to be -70 mV. If five EPSP’s (each with a voltage of 2 mV) and three IPSP’s (each with a voltage of 1 mV) arise in a nerve cell at the same time, what would the resulting graded potential be? a. In the above question, if the resulting graded potential reaches threshold, what channels would open? b. When an action potential reaches an axon terminal, what channels would open?

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...

When the membrane potential of a cell is equal to the equilibrium potential of sodium (+60mV), the intracellular concentration of sodium is smaller than the extracellular concentration. I'm probably just missing a tiny link. But I can't seem to understand why this is WRONG. Will the sodium concentration be equal on both sides? thx in advance!
