True regarding Na+ ion
Ans. (c) Responsible for depolarization(Ref: Guyton, 13th ed/p.65)Option a - Sodium ion is not Responsible for Donnan effect. This effect is due to non-diffusible anions like proteinsOption b - potassium ion is responsible for RMPOption d - many substances require sodium for their transport through secondary active transport processes
Responsible for Donnan effect
Responsible for resting membrane potential
Responsible for depolarization
Dose not help other ions in transport
