A)The Na⁺/K⁺ pump directly uses ATP
B)The Na⁺/K⁺ pump creates an electrical disequilibrium.
C)The Na⁺/K⁺ pump creates chemical disequilibrium.
D)It is expressed only on select cell types
E)The Na⁺/K⁺ pump is an example of counter transport.

Question

Quizplus · Accepted Answer

The sodium-potassium pump directly uses ATP to transport Na⁺ and K⁺ ions across the membrane, creating both electrical and chemical disequilibrium. It is an example of counter transport as it moves Na⁺ and K⁺ in opposite directions. It is expressed in nearly all cell types, not just select ones.
