Ch. Ex. 2 - Calculating Chemical and Electrochemical Gradients Established By the Na+/K+ ATPase Pump
Be sure to answer all parts. 6APaed across the membrane: 110 eyeles of A total of 6 Na K ATPase pumps each carry out 110 cyeles of active transport. Caleulate the cycles of active transport. Calculate the of molecules consum number of molecules consumed and transported across the membrane: TP consumed: Net molecules of Na transported: transported: Net charge differential extracellular: intracellular: Net molecules of K molecules of K' transported.Explanation / Answer
total 6 Na/K pump and each carries out 110 cycles of active transport. so total 110*6 = 660 cycles.
each cycle consumes 1 ATP molecule so total 660 ATP will be consumed.
each cycle 3 Na outside and 2 K transported inside so total
3*660 = 1980 Na molecule move outside.
and 2*660 = 1320 K move inside.
net charge differential extracellular: intracellular = 1980:1320 = 3:2
