What would most likely happen if the Na+K+ Pump (ATPase) stopped functioning in the cell?
A. The cell would swell by taking up water.
B. The cell would shrink by pumping out water.
C. The inside of the cell would be more negative.
D. Nothing would happen to the cell.
Homework Answers
ANS. A. The cell would swell by taking up water.
Every cycle of an Na/K pump removes three cations (3 Na+) for every two (2 K+) that it imports into the cell. Thus there is a net loss of one cation for every cycle of the pump. Therefore, without these pumps, the cell swells up.

In considering active transport by Na+-K+-ATPase, 3 Na+ are pumped out of the cell and 2 K+ are pumped in for each ATP that is hydrolyzed to ADP + Pi. Given a ΔG for ATP hydrolysis of -10 kcal/mol, and that V is -60 mV (more electronegative inside), and that the pump typically maintains the internal Na+ at 10mM, external Na+ at 145 mM, internal K+ at 140 mM and external K+ at 5mM, what is the efficiency of the...

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...

The Na+/K+ pump transports 2 K+ into the cell and 3 Nat out of the cell under the use of ATP. Under normal circumstances, the concentration of K+ inside the cell is 140 mm, while the [K] outside of the cell is 6 mM. The concentration of Nat inside the cell is 16 mM, while the [Na] outside the cell is 145 mm. The membranpotential is -0.07 V The temperature is 37°C/310,15K c) Calculate how much energy (kJ/mol it takes...

HW 11-1 Recall that the Na + concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Na + ions into the cell to the "uphill" transport of glucose into the cell. If the Na + concentration outside the cell ( [ Na + ] out ) is 149 mM and that inside the cell ( [ Na + ] in ) is 19.0 mM, and the cell potential is −...

What would most likely happen if M-cyclin is replaced by a nondegradable M-cyclin? A : The cell cycle would proceed as normal B : The cell cycle would not initiate and the cells would remain in G0. C : Cells would complete one cell cycle but would not start the next cell cycle. D : Cells would complete G1, S, and G2, but cannot enter the M phase. E : Cells would enter M phase but would not exit mitosis.
