Question

After a nerve impulse is produced by a neuron, what returns the neuron to its resting state?

• A. $Na+/K+$ pumps transporting ions across the membrane
• B. $Na+$ channels producing local depolarization
• C. $K+$ channels producing local hyperpolarization
• D. $Na+/K+$ pumps preventing ion transport

Answer 1

The correct option is A $Na+/K+$ pumps transporting ions across the membrane

• In the processes of Sodium-Potassium Pump, there is the process of moving sodium and potassium ions across the cell membrane.
• It is an active transport process involving the hydrolysis of ATP to provide the necessary energy.
• It involves an enzyme referred to as Na+/K+-ATPase. Hence, After a nerve impulse is produced by a neuron, what returns the neuron to its resting state Na+/K+ pumps transporting ions across the membrane. So, the correct answer is 'Na+/K+ pumps transporting ions across the membrane'.
