### Step-by-Step Solution: 1. **Understanding Resting Potential**: - Resting potential refers to the electrical charge difference across the neuronal membrane when the neuron is not actively transmitting a signal. It is typically around -70 millivolts (mV). 2. **Role of Sodium-Potassium Pump**: - The sodium-potassium pump (Na+/K+ pump) is crucial in maintaining this resting potential. It actively transports ions across the neuronal membrane. ...

What is a resting potential ?

A : The imbalance in the concentration of Na^(+), K^(+) and proteins generates the resting potential. R : To maintain the unequal distribution of Na^(+) and K^(+) , the neurons use pumps .

What is true of resting potential ?

[A] : Most of the solutes in ECF and cytoplasm are electrolytes, i.e., electrically charged par- ticles or ions. Maintenance of an equilibrium between intracellular fluid and ECF is vitally essential for all cells. [R]: This osmotic equilibrium is maintained by sodium and potassium pump of the cells. It operates with the help of a Na^+, K^+ ATP as enzyme located in the cell membrane.

Na^(+) is absorbed in the intestine with the help of the sodium pump of the cell membrane.

Na^+ - K^+ pump is found in membranes of many cells like nerve cells. It works against electrochemical gradient and involves an integral protein ATPase. At the cost of one ATP, ionic gradient across the resting member is maintained by Na^+ - K^+ pump by transporting
