I did parts 1 and 2 ONLY NEED HELP WITH C

  1. This question deals with equilibrium potentials and ion movement. Show all of your calculation.
    1. Calculate the Equilibrium potentials for the following 2 ions.
      1. Na+ concentration inside a cell is 10 mM and outside the cell is 140 mM.
      2. K+ concentration inside a cell is 145 mM and outside the cell is 4.5 mM.
    2. The Vm for this cell is -16 mV.
      1. If a Na+ channel opens, which direction would the Na+ ions move?
      2. If a K+ channel opens, which direction would the K+ ions move?
    3. If the conditions are the same as above at which membrane potential would you expect the movement of the Na+ and a K+ions to cancel each other out and there be no net change in membrane potential? Explain your answer based upon the ions and equilibrium potentials?

    1. Animal cells have a Na,K pump that couples the energy of ATP hydrolysis to transport 3 Na ions out of the cell and 2 K ions into the cell. Inside astrocytes, the concentration of Na is 20 mM and the concentration of K is 130 mM. The extracellular concentrations of Na and K are 145 mM and 5 mM, respectively. Calculate the energy required for the transport of Na and K , with this stoichiometry; assume that the cell...

    Upon fertilization, the eggs of many species undergo a rapid change in potential difference across their outer membrane. This change affects the physiological development of the eggs. The potential difference across the membrane is called the membrane potential, Vm, which is the potential inside the membrane minus the potential outside it. The membrane potential arises when enzymes use the energy available in ATP to expel three sodium ions (Na+) actively and accumulate two potassium ions (K+) inside the membranemaking the...

    Imagine you insert a stimulating electrode into a "typical" neuron in your arm, so that you can inject any amount of depolarizing or hyperpolarizing current that you want into the cell. Assume for the sake of this question that doing so will not alter the ionic concentration gradients in your tissue, kill the cell, or damage any of the normal components of the cell. Is there any way that you could create a situation where K^+ ions were diffusing on...
