Explain the general mechanism for the simultaneous transport of Na+ and K+ by the Na+/K+ ATPase (aka. Na+/K+ pump) describing: The result of this transport on the concentrations of Na+ and K+ inside and outside of the cell How the binding of Na+ and K+ are related to the conformation changes on the protein We discussed F-type pumps, which can also function in the reverse direction (i.e. ATP synthase). Explain how this protein can function both as a pump and...

How is it that the CL-/HCO3- exchanger operates in one direction in tissues and in the opposite direction in the lungs?

How would you explain fluid and electrolyte imbalances with Na+, K+, Mag+, Cl-, Ca+, P? And what would the signs and symptoms be if a person were to be hypo or hyper? And what would be the nursing interventions? (Not sure if you know, but I thought I would ask just in case.) Thank you

Furosemide: Relative to normal, what would happen if the drug furosemide inhibits Na+/K+ and Na+/Cl- symport channels in the thick segment of the ascending limb of the nephron tubule? Explain your reasoning for each. What would happen to water loss from the descending limb? Why. What would happen to the osmolarity of the filtrate inside the bottom of the nephron loop? Why? What would happen to the loss of salt (NaCl) from the thin segment of the ascending limb. Why?

The initial concentrations of Na+ and Cl− in the reaction below are each 0.0843 M. If the initial concentration of NaCl is 0 M and the equilibrium constant is Kc=8.21 under certain conditions, what is the equilibrium concentration of Na+? NaCl(aq)⇌Na+(aq)+Cl−(aq)

Which of the following correctly depicts the mechanism of the Na+/glucose co-transporter discussed in class? Select one: a)Both the Na and the glucose must bind which allows Na to move against its gradient because glucose is moving down its gradient. b)Glucose is pushed against its gradient because Na will be moving with its electrochemical gradient. c)This transporter binds Na on the outside of the cell, then ATP adds on a Phosphate, which changes the confirmation and open to cells interior...

1. For a Na+-Cl- ion pair, attractive and repulsive energies and , respectively, depends on the distance between the ions , according to and . a) Determine the equilibrium spacing and the magnitude of the bonding energy . b) Determine the theoretical elastic modulus. c) When the crystal is heated, constituent atom vibration increases and thus bonding becomes loose and the equilibrium distance lengthens. Plot the linear thermal expansion coefficient curve on the potential curve and derive the expression as...
