Question
A cell membrane is more permeable to K+ than Na+. What would happen if the membrane was more permeable to Na+ than to K+?
Due to the increased movement of Na+ outward, the membrane potential would become more negative.
Due to the decreased movement of K+ outward, the membrane potential would become more positive.
Due to the increased movement of K+ inward, the membrane potential would become more positive.
Due to the increased movement of Na+ inward, the membrane potential would become more positive.Due to the increased movement of Na+ outward, the membrane potential would become more negative.
Due to the decreased movement of K+ outward, the membrane potential would become more positive.
Due to the increased movement of K+ inward, the membrane potential would become more positive.
Explanation / Answer
Answer.
Right Ans. = Due to the increased movement of Na+ inward, the membrane potential would become more positive.
Beacuse Na+ acticvated and inactivated Gated channels are present in menbrane to prevent the inward movement of Na+ and the Membrane tries to maintain its Potential Negative by extruding more K+ outside.
There is a Na+/K+ pump which pumps, 2 Na+ inside and 3 K+ outside. To maintain Negative Potential of Membrane.
This Negative Potential is Biologically Important.
