Chapter 6, Problem 8CP
Summary Introduction
To review:
The physiological significance of sodium-potassium pumps.
Introduction:
Active transport takes place against the concentration gradient and requires the expenditure of energy. The movement of molecules occur from a region of lower concentration to the region of higher concentration. Sodium-potassium pumps are found in all the cells of the body and these are primary active transport carrier.

HINT: Remember there are many more K+ leaky channels than Na+ on most excitable cell membranes. The rate of K+ movement in or out of the cell would not be affected. The rate of Na+ influx, i.e., movement into the cell, would be higher than normal. The rate of K+ efflux, i.e., movement out of the cell, would be higher than normal. The rate of K+ efflux, i.e., movement out of the cell, would be lower than normal.arrow_forwardCalculate the driving force for Na+, K+, and Ca2+ current in a neuron under physiological conditions.arrow_forward

Provide three possible mechanisms by which these conditions may stimulate rennin secretion. What are the consequences of increased rennin secretion that lead to increased aldosterone secretion?
