16. Which one of the following would occur as a result of the inhibition of Na/K/ATPase?
a) Decreased intracellular Na concentration
b) Increased intracellular K concentration
c) Increased intracellular Ca concentration
d) Increased Na-glucose cotransport
e) Increased Na-Ca exchange
Answer: c) Increased intracity Ca concentration
The answer is C, inhibition of Na/K ATPase leads to an increase in intracellular Na concentration, increased intracellular Na then leads to decreased Na gradient across the cell membrane, thereby inhibiting the Ca/Na exchange and causing an increase in intracellular Ca concentration. This is the basis of the major mechanism of action of cardiac glycosides like Digoxin.
17. The rate of conduction of action potentials along a nerve will be increased by:
a) Stimulating the Na-K Pump
b) Inhibiting the Na-K Pump
c) Decreasing the diameter of the nerve
d) Myelinating the nerve
e) Lengthening the nerve fiber
Answer: d) Myelinating the nerve
The answer is D, myelin insulates the nerve thus increasing conduction velocity; action potentials can only be generated at the nodes of Ranvier, where there are breaks in the insulation. The activity of the Na/K pump does not directly affect the conduction or formation of action potentials. Decreasing nerve diameter would increase internal resistance and therefore slow down conduction velocity.
